AVAudiosession with allowbluetooth option prevents to listen bluetooth button events

I have a VoIP call application. I m trying to add functionality that when the user connected bluetooth to device and hit the bluetooth button call might be answered. I added options that when incoming call received incoming ring should play in bluetooth also.

 let audioSession = AVAudioSession.sharedInstance()
            try audioSession.setCategory(AVAudioSession.Category.playAndRecord, mode: .spokenAudio, options:[.defaultToSpeaker,.allowBluetooth,.allowBluetoothA2DP])
                    try audioSession.setActive(true, options: .notifyOthersOnDeactivation)

and I added MPCommandCenter to listen bluetooth events ;

let rcCenter = MPRemoteCommandCenter.shared()
        rcCenter.nextTrackCommand.isEnabled = false
        rcCenter.nextTrackCommand.addTarget { _ in return .success }

        rcCenter.previousTrackCommand.isEnabled = false
        rcCenter.previousTrackCommand.addTarget { _ in return .success }

        rcCenter.togglePlayPauseCommand.isEnabled = true
        rcCenter.playCommand.isEnabled = true
        rcCenter.pauseCommand.isEnabled = true
        rcCenter.stopCommand.isEnabled = true

        rcCenter.togglePlayPauseCommand.addTarget{ [unowned self] event in
            print("togglePlayPauseCommand")
            return.commandFailed
        }
        rcCenter.playCommand.addTarget{ [unowned self] event in
            print("playCommand")
            return.commandFailed
        }
        rcCenter.pauseCommand.addTarget{ [unowned self] event in
            print("pause")
            return.commandFailed
      
        }
        rcCenter.stopCommand.addTarget{ [unowned self] event in
            print("stop")
            return.commandFailed
        }

When I remove bluetooth related options from audioSession.setCategory I can listen to events. But when I put them again, events don't work. I also tried UIResponder but had no success;

UIApplication.shared.becomeFirstResponder()
UIApplication.shared.beginReceivingRemoteControlEvents()

and

override func remoteControlReceived(with event: UIEvent?) {

        if let rc = event?.subtype{
         
           print("OVER HERE")
        }
  }

any idea will be appreciated.
