How to know if an object is grabbed or not in Oculus Quest?

I have a simple scene in which there is OVRPlayerController and gameobjects with OVRGrabbable script attached to them. What I want to do is, when the player grabs an object I want to change its color. How can I achieve this? I have absolutely no idea how the OVRGrabbable script is letting the object know if it is grabbed or not. I will be looking into it more, and if I come up with the answer I’ll be sure to post it. Meanwhile any help will be appreciated very much. Thank you

One way is to extend OVRGrabbable and override GrabBegin() and GrabEnd().

What do you mean by extend?

диd you find way?
