Physics.OverlapSphere - do an action only if there are no other gameobjects with tagX around

Hello there!

I try to cast a sphere around a hit.point and identify, whether there are already other objects within that sphere with a specific tag (XMark). If not, an object should be spawned. Does Physics.OverlapSphere maybe not work if instantiated objects? Or am i getting it wrong? From what i find on the internet this should work :-/ Maybe anyone of you can give me a hint how i can do it right?

Thanks a million!

Here is the Code:

  MarkXPosition = hit.point;
   
                // Physics.OverlapSphere(center, radius);
                Collider[] MarkXFindSphere = Physics.OverlapSphere(MarkXPosition, 5f);
                Debug.Log("Checking if XMarks exist closeby ");

                foreach (Collider Test in MarkXFindSphere)
                {
                    if (Test.gameObject.tag != ("XMark"))
                    {
                        Debug.Log("No XMarks found nearby, spawning one");
                        Instantiate(XMark, MarkXPosition, XMark.transform.rotation);
                    }

                    else
                    {
                        Debug.Log("An XMark already exists nearby! Not spawning XMark");
                    }

                }

I guess I found a solution: just in case someone has a simular problem I’m posting it here. The code seems to check for all objects without the tag and spawns one Object for each of them. So I helped myself with adding a counter whenever one object was found with the tag the instantiate wouldnt run since the counter isn’t 0 anymore.

MarkXPosition = hit.point;

                // Physics.OverlapSphere(center, radius);
                Collider[] MarkXFindSphere = Physics.OverlapSphere(MarkXPosition, 2f);
                Debug.Log("Checking if XMarks exist closeby ");

                foreach (Collider Test in MarkXFindSphere)
                {
                   
                    if (Test.gameObject.tag == ("XMark" ))
                    {
                        XmarkAmount = XmarkAmount +1;
                        return;
                    }
                    else
                    {
                        XmarkAmount = 0;
                    }
  
                }

                if (XmarkAmount == 0)
                {
                    Debug.Log("No XMarks found nearby, spawning one");
                    Instantiate(XMark, MarkXPosition, XMark.transform.rotation);
                }
