using MRTK implementation add listener codes

Question

contactDetection.onTouch.AddListener(MyCallback);
contactDetection.onFirstTouch.AddListener(DoThisOnFirstTouch);
contactDetection.onLastUntouch.AddListener(DoThisOnLastUntouch);

I was using these lines of code for HPTK for oculus, but I want to do the same for MRTK. Can someone help me? How can I do that?

I was trying to know when my object was touches and left. When my cursor first touches my object, then when it lefts the touch of my object.

In MRTK, you can use Interactable or ObjectManipulator to detect if an object is being touched. For more information, you can refer Buttons - MRTK 2 | Microsoft Learn and Object manipulator - MRTK 2 | Microsoft Learn. Regarding whether it's the first touch, maybe you can add a counter manually.
