Hover event with VIVE Controller

I have made a start with the BP. Not knowing how to connect the textrender to the target of the toggle visibility. This is the BP of the button-01 (Cylinder)

I also can’t find the laserpointer in my level? So I chose the arc spline (I guess this is the laserbeam of the controller (or am I wrong?)

Attached the screenshots of my level and the BP so far…
