How to discern the location of a file/tab in Microsoft Teams from the tab’s URL

I have a situation where someone has added a tab to a team in Microsoft Teams, and the tab appears to lead to a file… except the file is not one that is hosted/stored within that Team. The issue is that no one in the team appears to have access to the file, including the owners.

There are no documents in the team’s Files folder or the team’s SharePoint site’s Documents folder (or any other folders) that match the name of the file link or that have unique permissions (in other words, all team members/owners have access to all the files uploaded to the team itself).

When I copy the tab’s URL, Teams frustratingly hides the actual file URL (e.g. a SharePoint or OneDrive URL, like I expected) with an esoteric Teams-specific URL:

https://teams.microsoft.com/l/entity/1c256a65-3333-2222-1111-123412341234/_djb2_msteams_prefix_792457649?context={"channelId":"19:a7d8031d133243a7aabc9ffdfc75b94f@thread.tacv2"}&groupId=4263c38e-333-2222-1111-333322221111&tenantId=e80adaf3-3333-2222-1111-123412341234

(the GUIDs have been modified in the above URL for security reasons)

Is there a way I can tell (e.g. from the Teams Admin Center or via PowerShell) from the URL above where that given URL points to/where that file is located?
