XR Ray Interactor's Hide Controller On Select not implemented?

[Godatplay]

Hide Controller On Select didn't seem to do anything, and I can't find any implementation for it outside of the editor class for XRRayInteractor.

Same problem. try to see there: https://fistfullofshrimp.com/unity-vr-direct-interactor/

"To use this normally, all you need to do is click the box and make sure that the XR Controller Script on the left or right hand controller is instantiating the hand prefab found here.
The only problem is that we have a new Hand script that both animates our and instantiates it. If we choose to use this script, checking the Hide Controller On Select option will do nothing. To fix that, we’ll need to add a few things to our hand script."
