SharePoint file Permission Collection does not show Group Membership?

Question

Hi, in article “List sharing permissions on a driveItem” (List who has access to a file - Microsoft Graph v1.0 | Microsoft Learn), there is a code snippet to get the file permissions:

result = await graph_client.drives.by_drive_id('drive-id').items.by_drive_item_id('driveItem-id').permissions.get()

In the result, I can see the read/write permissions for Team Site Owners, Excel Services Viewers, Team Site Visitors, Team Site Members.  However, I added the file to a Group called HR, but cannot find the permission in the Permission Collection.  Am I looking in the right place?

Below is the output that includes Permission Collection
