Meta Building Blocks - Poke interaction - how to trigger event

In the previous Unity XR Interaction tools the push button example had a Script called XR Simple Interactable which had the “Select Entered” option in which I could place GameObjects and I could choose GameObjective.Set.Active.
Now in the new Meta Building blocks I am not able to find how to do it.
Does anyone have a clue of where is this option now or how do I work around?
