Hello My app record voice with Record_Engine class(AvaudioEngine). Problem: Even though i made my app go to background, app return to inactive state in few seconds(about 3 seconds after watch screen locked). Example: How can i leave my app background. like built-in record app. and my recorder class is here. //Recorder.swift class Record_Engine : ObservableObject {    @Published var recording_file : AVAudioFile!    private var engine: AVAudioEngine!    private var mixerNode: AVAudioMixerNode!        init() {      setupSession()      setupEngine()    }            fileprivate func setupSession() {      let session = AVAudioSession.sharedInstance()      do {        try session.setCategory(AVAudioSession.Category.playAndRecord, mode: .default)        try session.setActive(true)      } catch {        print(error.localizedDescription)      }    }        fileprivate func setupEngine() {      engine = AVAudioEngine()      mixerNode = AVAudioMixerNode()      mixerNode.volume = 0      engine.attach(mixerNode)      makeConnections()      engine.prepare()    }    fileprivate func makeConnections() {      let inputNode = engine.inputNode      let inputFormat = inputNode.outputFormat(forBus: 0)      engine.connect(inputNode, to: mixerNode, format: inputFormat)      let mainMixerNode = engine.mainMixerNode      let mixerFormat = AVAudioFormat(commonFormat: .pcmFormatFloat32, sampleRate: inputFormat.sampleRate, channels: 1, interleaved: false)      engine.connect(mixerNode, to: mainMixerNode, format: mixerFormat)    }        func startRecording() throws {      let tapNode: AVAudioNode = mixerNode        let format = tapNode.outputFormat(forBus: 0)        self.recording_file = try AVAudioFile(forWriting: get_file_path(), settings: format.settings)        tapNode.installTap(onBus: 0, bufferSize: 8192, format: format, block: {          (buffer, time) in          do {try self.recording_file.write(from: buffer)}          catch {print(error.localizedDescription)}        })        try engine.start()    } }

In watchos we can back to clock(homescreen) by two way. click dial cover screen with hand My app record audio with avaudioengine. But when i try to back to clock by two way written above. App didn't stay in background, but appear in screen with inactive state. For example, built-in voice recording app excuted in background when we go back to clock by clicking dial. And the app also go back to clock when covering screen with hand. How can i make my app stay in background when dial clicked like built-in recording app.
