How to make the enemy fire a few bullets and make him stop for a few seconds to reload

Hi, I have a simple patrol script for enemies, they just patrol an area and when the player enters their range they start firing. The problem, however, is that they shoot bullets endlessly, what I would like to do is to fire only 3 bullets and then wait a few seconds, and then continue firing, how could I do?

I also leave attached the script I am using

{ public float walkSpeed; public float range;
public float timeBTWshots; float distToPlayer; public float bulletSpeed;

 bool mustPatrol;  
 public Rigidbody2D rb;
 private bool mustTurn, canShoot;   
 public Transform groundCheckpos;
 public LayerMask groundLayer;

 public Collider2D bodyCollider;
 private Animator anim;

 public Transform player;
 public GameObject Bullet;
 public Transform shootPos;







 void Start()
 {
     mustPatrol = true;
     canShoot = true;
     anim = GetComponent<Animator>();
 }

 void Update()
 {
     if (mustPatrol)    
     {
         Patrol();
         anim.SetBool("runshoot", true);
     }

     distToPlayer = Vector2.Distance(transform.position, player.position);
    
     if (distToPlayer <= range)
     {
         if (player.position.x > transform.position.x && transform.localScale.x < 0||player.position.x<transform.position.x && transform.localScale.x>0)
         {
             Flip();
         }

         mustPatrol = false;
         
         if (mustPatrol == false)
        
         {
             anim.SetBool("runshoot", false);
             rb.velocity = Vector2.zero;
             anim.SetTrigger("shootenemy");
         }

         if(canShoot)
         StartCoroutine(Shoot());
      


      
     }
    
     else 
     {
         mustPatrol = true;
     }

 }

 void FixedUpdate()
 {
     if (mustPatrol)
     {
         mustTurn = !Physics2D.OverlapCircle(groundCheckpos.position, 0.1f, groundLayer);
     }
 }
 void Patrol()
 {
     if (mustTurn||bodyCollider.IsTouchingLayers(groundLayer))
     {
         Flip();
     }
     rb.velocity = new Vector2(walkSpeed * Time.fixedDeltaTime, rb.velocity.y);  
 }
   
 void Flip() 
 {
     mustPatrol = false;
     transform.localScale = new Vector2(transform.localScale.x * -1, transform.localScale.y);
     walkSpeed *= -1;
     mustPatrol = true;
 }

 IEnumerator  Shoot()
 {
     canShoot = false;

     yield return new WaitForSeconds(timeBTWshots);
     GameObject newBullet = Instantiate(Bullet, shootPos.position, Quaternion.identity);

     newBullet.GetComponent<Rigidbody2D>().velocity = new Vector2(bulletSpeed * walkSpeed * Time.fixedDeltaTime, 0f);

     canShoot = true;

    
 }

}
