[BUG] The remote server returned an error: (401) Unauthorized

[KawaKode]

Reporting an Issue or Missing Feature

I recently converted a script to use the Entra ID registered app authentication because the old interactive credentials one is deprecated.
Since then, I always get "The remote server returned an error: (401) Unauthorized" even tho I granted every API permission that would be relevant to the script (which is attached to this ticket).

API authorizations

I'm using a cert to authenticate.

Expected behavior

it should be able to generate a permission report of the targeted site.

Actual behavior

The remote server returned an error: (401) Unauthorized.

Steps to reproduce behavior

Use the script, it will prompt you for any needed inputs (it will ask you your tenant url and site name, you still need to edit the variable $tenantUrl with your tenant FQDN, without https://).

What is the version of the Cmdlet module you are running?
