I've got a similar situation to https://learn.microsoft.com/en-us/answers/questions/692704/is-it-possible-to-use-ms-graph-sites-selected-appl

I am attempting to share a DriveItem via the Graph API to external users. I am connecting to the Graph API using a ClientCertificateCredential with Sites.Selected scope.

Is this something that is supported? Or are the permissions listed here (https://learn.microsoft.com/en-us/graph/api/driveitem-createlink?view=graph-rest-1.0&tabs=http) up-to-date and either Files.ReadWrite.All or Sites.ReadWrite.All permissions are actually required?

    Hi @Justin,

    Sites.Selected permission is a more granular permission than Files.ReadWrite.All. If you want to create a sharelink by graph. You will need at least Files.ReadWrite.All permission. So if the role in Sites.Selected permission is lower than Files.ReadWrite.All permission, we will be unable to create the sharelink.

    Here is the document for more details
