How to rotate the player towards a Vector2?

When the player is selected, and you click on the world. The player will move there. However, they do not rotate in the direction they are going. Here is my code:

 public class UnitBehavior : MonoBehaviour
 {
     //Movement
 
     public bool isSelected;
 
     public float moveSpeed;
 
     private Vector3 moveTarget;
 
     public bool isMoving;
 
     //Info
 
     public float health;
 
     public float combatStress;
 
     public string unitName;
 
     
 
     
 
     // Start is called before the first frame update
     void Start()
     {
         moveTarget = transform.position;
     }
 
     // Update is called once per frame
     void Update()
     {
         //Health
 
         if(health <= 0)
         {
             //dies
         }
 
 
         //Movement Order
 
         if (Input.GetMouseButtonDown(1) && isSelected)
         {
             moveTarget = Camera.main.ScreenToWorldPoint(Input.mousePosition);
             moveTarget.z = transform.position.z;
         }
 
         transform.position = Vector3.MoveTowards(transform.position, moveTarget, moveSpeed * Time.deltaTime);
 
 
     }
 
 
     //Selection
 
     void OnMouseDown()
     {
         if(isSelected == false)
         {
             isSelected = true;
         } else if(isSelected == true)
         {
             isSelected = false;
         }
     }
 
 
 
 
     //Enemy in view
 
     void OnTriggerEnter2D(Collider2D other)
     {
         if (other.gameObject.CompareTag("Enemy"))
         {
             
         }
     }
 
 }
