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"
