Check if a Collider2D is hit by a Trigger Collider2D

Hello, i have a problem while trying to detect a "hit" between a Sword that has a Trigger Collider2D, and an Enemy that has a Collider2D, while trying to manage it in the Enemy's script.

I've been looking for similar answers but i cant find anything similar to :

 void OnEnterCollision2D(TriggerCollider collider)
 {
     //Whatever 
 }

So, basically, i just want -The Enemy- in his own script to detect when it's been hit by a trigger collider
