I think I could workaround this by listening to iOS_BroadcastStopped notification from CFNotificationCenter

(DarwinNotificationCenter is extended by following https://gist.github.com/tomlokhorst/7fe49a03b8bac960eeaf2b991faa3680 so that callback can use async)

   func performAsyncTask() async {
        do {
            try await room.localParticipant.setScreenShare(enabled: false)
        } catch {
            print("An error occurred while updating screen share")
        }
  }

 func notificationCallback() {
        DispatchQueue.global().async {
            Task {
                await performAsyncTask()
            }
        }
    }

DarwinNotificationCenter.shared.addObserver(name: "iOS_BroadcastStopped", callback: notificationCallback)

Probably I can address fix for #444 with similar approach

I could workaround like this

 @State var darwinNotificationCenterObservation: DarwinNotificationObservation?

 // Define an async function to perform the async task
    func performAsyncTask() async {
        do {
            try await room.localParticipant.setScreenShare(enabled: false)
        } catch {
            print("An error occurred while updating screen share")
        }
    }
    
    // function that matches the C function pointer type
    func notificationCallback() {
        // Dispatch to handle async code
        DispatchQueue.global().async {
            Task {
                await performAsyncTask()
            }
        }
    }
    
    
    func setupNotifications() {
        // We need to store the value in variable/state to keep notification active.
        darwinNotificationCenterObservation = DarwinNotificationCenter.shared.addObserver(name: "iOS_BroadcastStopped", callback: notificationCallback)
    }
