Admin reporting of third-party app usage in Teams

[Gurdev Singh]

Anyone know of audit or log history available of a third-party app being used in Teams. What sort of reporting is available to an admin to check what data third party app has been accessing, app connection history etc.

One option I know of is to check the app sign-in history under Enterprise Applications in Azure Portal. Is there any other logging available as to which data app is reading from a Team and when?

None really. If it's not in the audit log, there's hardly anything you can do. There's a new, more robust app attestation program coming out, in case you have missed the Ignite news, that might help alleviate some of the uncertainties around "what a given app can access in my tenant", but that's still not the same as being able to report on the actual app usage.
