Native Android Oculus Go App--ugrade for quest 2

Hi,

I had an app developed for oculus go using Native Android and Oculus(NO Unity or Unreal). as on the page:

https://developer.oculus.com/documentation/native/android/mobile-studio-setup-android/

What changes should i do to the app to make it work on quest?(it is a 3dof  experienceand I want it to remain as 3dof but run in quest 2)
