Set VR trigger to correspond to a mouse click

Hey,

I am developing my first VR experience and I’m using Vive xr elite. I needed to make a pointer because it’s not available by default. The thing I want to do is set the trigger of the controller to correspond to the left mouse button or “click event” so the pointer would have the functionality to select just like a mouse click. How to set this up in the VRPawn blueprint?
Thanks in advance!
