How to have separate colliders in a single tile map?

I have created a tile map which has a bunch of tiles which are supposed to get destroyed when hit by a ball, I added a tile map collider and the green boxes seem to appear around every tile separately but when I tested my game, the ball would destroy all the tiles even if it just hit one of them. I would like the tiles to be destroyed separately however but am not sure how to fix this issue. Here is my code to destroy the tiles if it helps :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class BallControls : MonoBehaviour
 {
     void OnCollisionEnter2D(Collision2D collisionBall)
     {
         if (collisionBall.gameObject.CompareTag("TileBlocks"))
         {
             Destroy(collisionBall.gameObject); ;
         }
     }
 }

Thanks for any help I recieve!
