Work already done:
- moving the New Room screen to a different endpoint
- fetching public rooms using the post API
- displaying public rooms
Suggestion for user interaction:
1. click on room
2. open bottomSheet with information and join button
3. click "join" to join room
If the room was created successfully,
the wizard automatically saves the room data on disk.
This allows it to be cached,
even if the user loses internet connection
right before the wizard exists.
That way the room will be cached.
