I am trying to update a SharePoint CSOM application to use the Microsoft Graph API.
The existing program used credentials (username + password) from the SharePoint CSOM to download documents from SharePoint using the System.Net.WebClient library. What I can’t work out how to pass the authentication details from Microsoft graph to SharePoint.

I’m trying to retrieve audit logs or activity reports related to sensitivity labels applied to files stored in SharePoint using the Microsoft Graph API. Specifically, I want to track when a sensitivity label is applied or changed on a file within SharePoint.
