Occupancy
Occupancy enables you to view the number of users currently online in a room. This feature can be used to display user counts to highlight popular, or trending chat rooms.
Subscribe to room occupancy
Subscribe to a room’s occupancy by registering a listener. Occupancy events are emitted whenever the number of online users within a room changes. Use the occupancy.subscribe() method in a room to receive updates:
val subscription = room.occupancy.subscribe { event: OccupancyEvent ->
println(event.toString())
}
