"These people will lose access soon" - but what these people have access to?

I should have done that before but I have set expiration policies only recently but still, users get a message that someone will lose access, but no further information is given about what resource exactly. It points only to the Site (OneDrive or other SharePoint site) but not to the file or folder.

Since the system knows exactly the day the external user will lose access, it must also know the resource associated with that day, why not providing it somewhere?
