In the official Microsoft documentation, I found that with the Graph webhook, you can receive notifications for permission changes for a file in a document library by inserting the prefer:includesecuritywebhooks parameter in the header when creating the subscription. I tried, but it only works for OneDrive and not for SharePoint. Can anyone tell me why and how to fix it?
