Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe income tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate as adjusted for discrete items arising in that quarter. The effective income tax rate was 0.5% and 1.0% for the three and nine months ended October 31, 2022, respectively. The effective tax rate was nil for each of the three and nine months ended October 31, 2021. The effective tax rate differs from the U.S. statutory rate primarily due to the full valuation allowances on the Company’s net domestic deferred tax assets as it is more likely than not that all of the deferred tax assets will not be realized.
