Pico 4 apk file

So I made app some time ago and it worked fine on android (although I had problem with moving around, used default commands, instead pinch hand gesture). Now I installed that apk file on Pico 4 and it works like charm, BUT. It open app and you look like a cinema mode in VR googles so there is no 360 or virtual reality (guess have to use virtual camera? ) and second there is again default controls.
So my question is what I have to do to make 360 VR apk file. And how to use Pico 4 joysticks to move around and use 3d objects etc? in other words how to make VR aplication?
Thanks in advance.
