Since 9/9/2024: change of authentication method to connect sharepoint with PnP interactively. 

Connect-PnPOnline -Url $siteUrl -Interactive 

This method is no longer supported.


Solution : interactive connection is only possible using the ClientID that now exists on our Gcloudbelgium tenant:

Connect-PnPOnline -Url $siteUrl -Interactive -ClientId 3e34f61d-ff19-4ce1-9a21-06e863877ade


Permissions : 

GraphDelegatePermissions "Group.Read.All"

SharePointDelegatePermissions "AllSites.FullControl"
