Cannot get Nintendo Switch Joycon accelerator motion data in iOS 16

Now I am using iOS 16 beta 6, I can get buttonA/buttonB is pressed event. but cannot get accelerator motion data info.

     //work
    buttonA?.valueChangedHandler = {(_ button: GCControllerButtonInput, _ value: Float, _ pressed: Bool) -> Void in
      print(">>> ButtonA tapped")
    }
    //work
    buttonB?.valueChangedHandler = {(_ button: GCControllerButtonInput, _ value: Float, _ pressed: Bool) -> Void in
      print(">>> ButtonB tapped")
    }
     
    // this is not works
    gameController.motion?.valueChangedHandler = { (motion: GCMotion)->() in
      print(">>>> motion data \(motion.acceleration.x) \(motion.acceleration.y) \(motion.acceleration.z)")
      if let delegate = self.motionDelegate {
        delegate.motionUpdate(motion: motion)
      }
    }

Is there any plan to support this?
