Just curious if anyone has been able to successfully integrate App Broker (2021 R2) with Azure/Intune Goverment Cloud?

We are trying to work through some errors:

• Error while getting master roles  Response status code does not indicate success: 401 (Unauthorized
• Failed to communicate with Intune, either the configuration settings are invalid or minimum permission is missing (Application.Read.All):  Response status code does not indicate success: 401 (Unauthorized).
