Require users to create a room in the database
before requesting a LiveKit token.
If user request an access token for a room that doesn't
exist in our db, its request would end in a 404 error.
Ensure that rooms must be registered by a user before they can be accessed.
By default, all created rooms remain public, allowing anonymous users to join
any room created by a logged-in user.
However, anonymous users cannot create rooms themselves.
