What oject/method calls "OnCollisionEnter2D"?,What object/method calls "OnCollisionEnter2D"?

Unity has these methods that can be used with colliders. These methods like "OnCollisionEnter" and "OnCollisionExit" are being called sometimes. I guess by the physics module of the UnityEngine, but is there anyway I can see exactly from where, like a file, it was called?

PS. I have already tried using a stacktrace, but this only seems to see the methods called in its own object.
