Publishing android apps on Quest

I want to discuss about how to port android app to Quest. At current state, I can connect my Quest to PC and install the app with Android Studio, that's fine.
I have read this article: Meta's CTO explains why Quest has so few Android apps 

And it states, that "They just need to ship the APK to us, and they may have to do some light modification, depending on how they want the control scheme to work, but maybe not even necessarily that much of that."
What could be the modifications? Making clickable content larger, so it can be controlled better?
Right now if I open the app, it opens in a small window and I need to enlarge it, so it's usable. Is it possible to open it enlarged already for the first time?
