I notice when a user joins a meeting, they have a numeric ID.
If they leave the meeting (either deliberately or because of internet problems) and return, the ID changes.
In my app, I am storing a “user state” against their name because the ID is not constant, but really, the name isn’t constant either (users can change their name, or multiple users could have the same name) so I was wondering how to get some kind of constant ID (account ID? or email?) from each user that will not change.
