How do i make the enemy face the player with this code?,How do I make the enemy face the player?

,I have tried a few ways to do this, but none seemed to work. How do i fix this or what should i do in order to make the enemy face the player?

public class Enemy : MonoBehaviour {

 public float speed;
 private Transform playerPos;
 private Player player;
 public GameObject effect;
 public int health = 4;


 void Start()
 {
     player = GameObject.FindGameObjectWithTag("Player").GetComponent<Player>();
     playerPos = GameObject.FindGameObjectWithTag("Player").transform;
 }

 void Update()
 {
    
     transform.position = Vector2.MoveTowards(transform.position, playerPos.position, speed * Time.deltaTime);

 }


 void OnTriggerEnter2D(Collider2D other)
 {
     if (other.CompareTag("Player"))
     
     {
         Instantiate(effect, transform.position, Quaternion.identity);
         player.health--;
         Debug.Log(player.health);
         player.score = player.score - 5;
         Destroy(gameObject);
     }

     if (other.CompareTag("Projectile"))
     {

         
         
             Instantiate(effect, transform.position, Quaternion.identity);
             Destroy(gameObject);
             player.score = player.score + 10;
         
     
         Destroy(other.gameObject);
     }
 }

 void FixedUpdate()
 {

     var playerPosition = playerPos.position;
     Quaternion rot = Quaternion.LookRotation(transform.position - playerPosition, Vector3.forward);

     transform.rotation = rot;
     transform.eulerAngles = new Vector3(0, 0, transform.eulerAngles.z);
 }

}
