iPhone to Android screen sharing

I have an Oculus Quest 2 VR headset that is wonderful, but i would like to screen share my iPhone to the headset for my drone app. But the Oculus is an Android device, so only Android folks can do it easily. There is an app (Airscreen) that can do it, but it costs $$. It would be great if Apple would make an App to communicate between the two platforms.

If there is a way now, please do let me know.

Thanks,

Bob
