Open VR/Steam VR sample code for oculus touch controlers?

[DRrrr]

I have  made a game in Unity for  htc vive, I would like to add controls for oculus touch

could somebody write a  sample  code   to show how to use oculus touch  controles  using OpenVR?

https://docs.unity3d.com/Manual/OpenVRControllers.html

Unity manual doesnt  have sample code

Thanks
