AR foundation tracked image events

Unity Engine

as the title suggests, I am looking for a way to trigger a function when an image is recognized.

with vuforia it used to be something like “OnTracked”
but since I went to the AR Foundation I have been looking for this and I have not found it, maybe I have overlooked something.

thanks for your help

Dilmer really has the best and clearest explanations for AR. Even better than downloading the Unity ARFoundation examples from Github:

HI, i realized that onimagechange events are not the same as tracking states, wich are better for showing or not prefabs for images, anyway i had to chech for visibility on camera in order to take away some object since traking state once gets tracking or limited never gets none, and its imposible to tell why is this happening
