How to use different and distinguish between different box colliders?

I have a game object with two box colliders attached, one to see the player and one to end the game. The player also has a box collider attached. //the box colliders public BoxCollider collider1; // longer box collider (trigger) public BoxCollider collider2;//smaller box collider (trigger) public BoxCollider colliderPlayer; //player box collider

 private void OnTriggerEnter(Collider collider1) //when the box collider is seen
     {
         Debug.Log("i see you"); //play a sound?
         StartCoroutine("VisibilityTime");
     }
 
     private void OntriggerEnter(Collider collider2)
     {
         Debug.Log("touch");
     }

I do not know how to distingwuish between the box colliders AND the second onTriggerEnter is never used for some reason?
