Item Activator if near player Script

Can anyone do something with this code to detect GameObjects when they are inactive? Thanks in advance <3

     // --------------------------------------------------
 
     void Start()
     {
         player = GameObject.FindWithTag("Player");
         activatorItems = new List<ActivatorItem>();
 
         StartCoroutine("CheckActivation");
     }
 
     IEnumerator CheckActivation()
     {
         List<ActivatorItem> removeList = new List<ActivatorItem>();
 
         if (activatorItems.Count > 0)
         {
             foreach (ActivatorItem item in activatorItems)
             {
                 if (Vector3.Distance(player.transform.position, item.itemPos) > distanceFromPlayer)
                 {
                     if (item.item == null)
                     {
                         removeList.Add(item);
                     }
                     else
                     {
                         item.item.SetActive(false);
                     }
