Oculus Go Character rotation by pointing controller to left/right

I hope somebody could help me with this (hopefully) simple problem.

I’m making my first VR app and I’m stuck with player/camera movement.

I have already got the player to move forward to direction where I’m looking by holding down the touch pad on top of controller, but I can’t figure out how to get the player rotating with anything else that just looking to different direction. I’d like to get the player slowly rotating when I point the controller to left/right.

Could anybody please help me with this?
