Someone tell me how to track the Back button on Android TV?
I tried this but it doesn’t work.

input.on(Input.EventType.GAMEPAD_INPUT, this.GamePadOnKeyDown, this);

and

input.on(Input.EventType.KEY_DOWN, this.onKeyDown, this);

Does this code not work?

if(e.keyCode = KeyCode.MOBILE_BACK){
    //
}

I’ll test it now.
does not work.
Even if I call only alert in the code at the moment I press the “back” button on the remote control, the alert window does not appear.

tvEventDown(){
   window.addEventListener(
     "keydown",
     (event) => {
            alert("keydown worked");
     },
     true,
   );
}

“OK” button is tracked.
