Question Material Changer Menu for OpenXR

i want to make a menu with different buttons that when u interact with them they change the material of the assigned game object.

where i can interact with my interactive rays from the XR toolkit attached to my controllers

like this tutorial i found on YouTube but isn't supported on XR, when i tried loading it in and knew how the script was written i couldn't apply it inside my project

and this asset is exactly what i am looking for in XR https://assetstore.unity.com/packages/tools/gui/vr-material-manager-92908

does anybody have a reference or information to give?

Thanks!
