Collision between triggered colliders

How can i detect collision between colliders that have Is Trigger > True and don’t have char controller and rigidbody?

And to go with myjean17’s explanation, you could use a script a little something like this:

function OnCollisionEnter(hit: Collision){
	if(hit.gameObject.tag == "tagOfObjectHitting"){
		//perform you code here!!!!!!
	}
}
