Accounting Policies [Abstract]
Basis of Presentation	*Basis of Presentation* The accompanying unaudited condensed financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”), and reflect all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the financial position as of June 30, 2021 and the results of operations and cash flows for the periods presented. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. Interim results are not necessarily indicative of results for a full year. The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K filed by the Company with the SEC on March 31, 2021.
Emerging Growth Company	*Emerging Growth Company* The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act, and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is (i) not an emerging growth company or (ii) an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Use of Estimates	*Use of Estimates* The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting periods. Actual results could differ from those estimates.
Concentration of Credit Risk	*Concentration of Credit Risk* Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which at times may exceed the federal depository insurance credit limit of $250,000. At June 30, 2021 and December 31, 2020, the Company had not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.
Risks and Uncertainties	*Risks and Uncertainties* Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position and results of its operations, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Financial Instruments	*Financial Instruments* The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheets.
Cash and Cash Equivalents	*Cash and Cash Equivalents* The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents.
Net Loss Per Share of Common Stock	*Net Loss Per Share of Common Stock* Net loss per share of common stock is computed by dividing net loss applicable to the shares of common stock by the weighted average number of shares outstanding for the periods. As a result of the redemption of Public Shares in November 2019, for the three and six months ended June 30, 2021 and 2020, the Class A shares have no specific redemption rights. As a result, net loss per common share is calculated by dividing the net loss by the weighted average number of Class A and Class B shares outstanding for the periods.
Income Taxes	*Income Taxes* The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB Topic ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of June 30, 2021 and December 31, 2020. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at June 30, 2021 and December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. The Company may be subject to potential examination by federal, state, and city taxing authorities in the areas of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions, and compliance with federal, state, and city tax laws. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. During the three and six months ended June 30, 2021 and 2020, the Company recorded income tax expense of $0.
Subsequent Events	*Subsequent Events* The Company evaluates subsequent events and transactions that occur after the balance sheet date for potential recognition or disclosure. Any material events that occur between the balance sheet date and the date that the financial statements were issued are disclosed as subsequent events, while the financial statements are adjusted to reflect any conditions that existed at the balance sheet date.
Recent Accounting Pronouncements	*Recent Accounting Pronouncements* The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have an effect on the Company’s financial statements.
