The meetingscollection has no tenant isolation. Any authenticated tl;dv user can query every meeting across every account on the platform. Each meeting record hands you the creator's email address, the conference ID (which is a joinable Google Meet or Teams room), the provider, the recording status, and timestamps.

I queried the Firestore meetings collection and saw there were 181,874 meeting records belonging to 84,312 unique users across 35,003 email domains.
