Get notified when someone joins a public room

Use Case

1. Sometimes people show up 10 minutes late to a call
2. Sometimes people randomly join a public room used for our weekly call and hope to reach me
3. Sometimes I write mails like: yes we can spontaneously discuss it today between 14:00 and 16:00 here <talk link>

Most of the time I will miss the people/calls in this case.

At least for 1 and 3 I always try to open a window on the second screen (if possible) and try to catch when someone enters the room. But this not always works and is super unreliable.

Possible solutions

1. Guest can't start a call but maybe show (optionally) a "request call" button they can click which notifies all moderators that someone is waiting in a public room
2. (Optional) a general notification every time someone joins a public room

A the moment I think I prefer option 1, because option 2 could generate to much noise. But I'm also happy with any other solutions which solves the use case. 🙂

On other solutions I sometimes saw a message like "you are the only one in the room, the owner was notified that you are waiting for him". But this were always solutions were you first had to complete a "setup" screen (enter your name, email address, etc) and than actively click on "join room". So it was a bit in between of 1. and 2. and has also the benefit that the notification can contain useful information like "Björn is waiting for you in room xyz". This would be also a nice option if we would introduce such a setup screen (which would also force people to finally set a proper name 😉 ).

No files, tests, or entry points are named. Start by tracing how guests join public rooms and how moderators currently receive room notifications. Done means agreeing on a notification flow, implementing the chosen solution, and covering the relevant guest and moderator cases.
