You can use this API - https://learn.microsoft.com/en-us/graph/api/shares-get?view=graph-rest-1.0&tabs=http Plug in the sharepoint link from chatMessage attachment and it will get you the download links you need.

Thanks for your quick reply.
I have tried this endpoint, and it seems to only work with files belonging to the user from whom my app have delegated permissions.
My case is:
- My app acts on behalf of user A (with delegated permissions)
- User B sends a Teams chatMessage with an attachment to user A
- Attachment is stored in the user B sharepoint/one drive
- Graph API (/shares/{shareIdOrEncodedSharingUrl}) returns an "unauthenticated" error
This exact same endpoint works for files stored in user A one drive.
It looks like I missed a permission but I don't know which one.
My app currently have these delegated permissions:
- Chat.ReadWrite
- Files.ReadWrite.All
- Sites.ReadWrite.AllCan you help me ?
- Up ?
