Transform Unity Inputs into Oculus Inputs

Hi, I am relatively new in this field hence asking for your kind advice.

I have developed a game that uses a lot of mouse clicks and hovers. No raycast.

So now I need to transform the game into a VR game using Oculus Quest. It was overwhelming for me to decide the direction for me to do this.

I understand the UIHelper, OVRPhysicsRaycaster can help me but I have yet to find a tutorial on how to convert my inputs to these.

So far I managed to pick&place some GameObjects using the OVRgrabbable and OVRGrabber.

Looking forward to work on GameObject transform using ray.

Please advise and include reference links. Have a nice day.
