Azure List/Update Entries 403 Forbidden

We are trying to build a pipeline to read and update user attributes in Azure. We have followed the Azure Application Setup instructions and given API Application permissions to our Application based on Update user guide.
[Application: User.ReadWrite.All, User.ManageIdentities.All, Directory.ReadWrite.All ]

We have also configured our Azure read and update snaps according to the Scopes and Permissions section at the bottom of the Azure Application Setup Guide.

We are continually receiving a 403 Forbidden error. Does anyone have a write-up or video showing how to perform this setup from end to end.

Are we perhaps missing a setting on our account, like an additional scope entry? If so, how do you enter multiple scopes?

Any suggestions would be appreciated.

Thanks
