I need help, I need that the projectile hit the the enemy that goes to him that is coming at him, my gun code from which I shoot

my code

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class spawnGuns : MonoBehaviour {

 public  Transform target;
 public GameObject Bullet;
 public  Transform point;
 

 float speed = 5f;

 public void Update()
 {
         } 



 void OnMouseDown()
 {
     GameObject bull = Instantiate(Bullet, point.position, point.rotation);
     bull.GetComponent<Rigidbody2D>().AddForce(point.transform.right * speed, ForceMode2D.Impulse);
     

     print("contact");
 }

}

the projectile I have has a rigid body komnonet and has weight, how can I convert the code so that I can calculate the future position of the troll and hit it
