Is your feature request related to a problem? Please describe.
Invite-only rooms are poorly-documented, and the UI doesn't make revocation clear.

The revoke button is easily-overlooked and doesn't clarify exactly what it does:
https://hubs-foundation.github.io/hubs/?path=/story/room-invitepopover--invite-link

Describe the solution you'd like

1. Make the Revoke button larger and expand the yes/no confirmation with info that existing users stay
2. Expand the documentation with a scenario showing how to deal with trolls

Getting hubs-docs back online will help — an old copy is online at Room Settings where it does describe the feature.

Describe alternatives you've considered
The official docs could be rewritten somewhat

Additional context
So far as I can tell, the only way people have found out about revoking invites and that existing users can stay is by asking on Discord and someone telling them. :-(
