Hi,
Thank you for your answer.
In this post it is described. https://learn.microsoft.com/en-us/graph/api/driveitem-delta?view=graph-rest-1.0&tabs=http.
I can see that that exist the option deltashowsharingchanges. It is for this purpose?
I can get changes when I change the permissions in the files or folders. But if I create a SharedLinks any change can be detected.
