attach

Attaches to the room to receive events in realtime.

If a room fails to attach, it will enter either the RoomStatus.Suspended or RoomStatus.Failed state.

If the room enters the failed state, then it will not automatically retry attaching and intervention is required.

If the room enters the suspended state, then the call to attach will reject with the ErrorInfo that caused the suspension. However, the room will automatically retry attaching after a delay.
