A* Pathfinding How to destroy seeker,A* Pathfinding What command to destroy seeker

My seeker doesn't get destroyed when approaching a target. I want Seeker to get close to the target and seeker disappears. I don't know what command I should use to order the seeker to destroy or enable=false.

Now I use the command

 public void OnTriggerEnter2D(Collider2D collision)
      {
          if (collision.gameObject.CompareTag("Player"))
          {
              destroy(gameobject);
          }
      }

into another script and it not working.

I'm a beginner who looks at the basics use 2D PATHFINDING on YouTube .
