PnP Management Shell EntraID app is Not deleted and get Application not found when connect-pnponline using user credentials

[shruti0985]

The user is connecting using user credentials and we see the error below:
Connect-pnponline - url -credentials

Message: AADSTS700016: Application with identifier '31359c7f-bd7e-475c-86db-fdb8c937548e' was not
found in the directory 'The [companyname]'.
This can happen if the application has not been installed by the administrator
of the tenant or consented to by any user in the tenant.
You may have sent your authentication request to the wrong tenant.

When we look at the Enterprise application we still see the app registration. This should have been deleted on Sept 9th. We do not see a way to manually delete it. Do we need to do anything about this app?

Right now the steps user plans to follow is:
1.Go ahead and update Windows Powershell to 7:

2. Then upgrade Pnp powershell to atleast 2.12.0.

3. Now, create the New Entra App ID:
