Any VR "Ray Interactor" docs/samples/tutorials/e.t.c in Unreal Engine?

In online manual i can see Ray interaction description as described on screenshot below.

I want to interact with 3D objects, by pointing hand/finger to them (ray casting)

But i cannot find any Blueprint nodes/samples/tuts how to deal with it. (in Unity there is a lot tutorials).

How to deal with ray interaction in UE?
