ios – Set off bluetooth headphone connection system display screen on Apple Watch

I am engaged on an app for the Apple Watch and I am seeking to implement performance much like what I’ve noticed within the Spotify app.

Particularly, I am taken with triggering the display screen that prompts the consumer to attach Bluetooth headphones if none are linked when trying to play audio.

I’ve hooked up a screenshot from the Spotify app which reveals the precise display screen I am referring to. This display screen seems when I attempt to play music with none Bluetooth headphones linked.

Here is a snippet of code I’ve tried in my SwiftUI app, which merely performs a sound by the Apple Watch speaker however would not set off the Bluetooth headphone connection display screen:

struct ContentView: View {
    var audioPlayer = strive! AVAudioPlayer(contentsOf: Bundle.important.url(forResource: "demo", withExtension: "mp3")!)

    var physique: some View {
        Button("Play Sound") {
            playSound()
        }
    }

    func playSound() {
        do {
            let audioSession = AVAudioSession.sharedInstance()
            strive audioSession.setCategory(.playback, mode: .default)
            strive audioSession.setActive(true)
            
            audioPlayer.play()
        } catch {
            print("Error: (error.localizedDescription)")
        }
    }
}

May anybody information me on how you can invoke this display screen?
Is there a selected API or system name that may deliver up this display screen on the Apple Watch?

Any pointers or code samples can be vastly appreciated.

Thanks!
