Microsoft Entra tenant locked out by Conditional Access policy

My Microsoft Entra tenant is currently locked out because I accidentally created a Conditional Access policy that blocks access.

The situation is:

-The Conditional Access policy targets the tenant's only Global Administrator account.

-The policy uses Block access and targets all resources.

-The Global Administrator account is now unable to access the Microsoft Entra admin center.

-There are no other Global Administrators in this tenant.

-I have another Microsoft account that I can access, but it does not have sufficient permissions in the affected tenant to modify Conditional Access.

-This is a lab/learning tenant.

I need assistance with tenant recovery / disabling the blocking Conditional Access policy so that I can regain access to the existing Global Administrator account.

Could a Microsoft support employee advise on the correct tenant recovery, Data Protection process for this situation?

Thank you.
