Unity UI for Oculus Go?

Hello everyone, I have started a new Unity project and imported the Oculus SDK for Unity. It has a sample UI scene with gaze control and 2 scripts - OVRInputModule.cs and OVRGazePointer.cs. I want to convert that gaze based UI control to using the Oculus Go controller as a laser pointer.

I looked at this post https://developer.oculus.com/blog/adding-gear-vr-controller-support-to-the-unity-vr-samples/ but it references other files that are not found in the Oculus SDK folder that I have. I tried to adapt some of the code and put it in the OVRInputModule.cs. It sort of works, but the linerenderer lags behind a frame or two.

Here is a link to the apk:

And to the whole project folder:

I also uploaded only the OVRInputModule.cs file:

And a pdf with trck changes from the original OVRInputModule.cs file:

I cannot believe that there are no scripts adapted to controller-based input. Am I missing something?

Thanks a lot in advance.
