At the moment, a transcript of the Live Feeds within a Live Event is not available.
However, Admin users can log back into the event after its conclusion by simply adding auth/login to the end of the event URL.
As an example, the URL would look like this:
https://events.unibuddy.co/university-of-Unibuddy/buddychat/auth/login
From there, Admins would be able to view the contents of each Live Feed.
