Port Quest app to other platforms

Hello,
I have app that developed for Quest Headsets with Meta XR Interaction SDK OVR Integration.
Now we have the task of porting the application to other headsets (android but not Meta) and PCVR. But I am a bit at a dead end because I do not understand in which direction to move. I do not understand whether I will have to abandon “Meta XR Interaction SDK OVR Integration” or not.

I will be glad to any information or maybe someone has had experience in solving similar problems?

What are the best tools to use for developing cross-platform VR applications?
