Spawn prefab randomly over polygon collider 2d

I have attached pollygon collider 2d on this gameObject.

This gameObject is parent of another gameObject (just small circle).

I want that small circle to randomly spawn somwhere on pollygon collider.

I tried something like this:

 private void GetBounds()
         {
             polygonCollider = transform.parent.gameObject.GetComponent<PolygonCollider2D>();
             bounds = polygonCollider.bounds;  
         }
     public void TargetSetPosition()
         {
             x = Random.Range(bounds.min.x, bounds.max.x);
             y = Random.Range(bounds.min.y, bounds.max.y);
     
             transform.localPosition = new Vector2(x, y);
          }
     
     private void Start()
         {
             GetBounds();
             TargetSetPosition();
         }

This script is attached to that small circle. In 80% cases is good result but sometimes it get weird something like this: alt text
