I dont know for certain.

I recall that if you were not signed in to an account on their Org, it would only show up with you as that you were a guest in the room, and you could not do much/anything without someone from that org authorising you.

I dont know if the token is long lived, i would hope its rotated frequently.

i also suspect that because it's above audible range, your average video compression might strip it out.
