Multiplayer gameboard: Each player can see the mouse pointer moving over the network

Hi!

I'm working in a multiplayer gameboard, and I'm trying to do that each player can see the mouse pointer moving over the network, represented by a typical hand image.

I only get that each hand image follows mouse pointer of each player, but anyone can see the mouse pointer moving over the network.

I'm trying with an empty Gameobject which have a canvas with two hand images (black and white) being part of the player prefab, or being part of the hierarchy, or instantiated by the player prefab and attaching one script like this:

void Update() {

   gameManager=FindObjectOfType<GameManager>();
   if(gameManager.count>=2)

   {

       if(photonView.IsMine)
         {
         
      WhiteCursorImage.enabled=false;
 
          Vector3 mousePos = (Input.mousePosition - 
         GameObject.FindGameObjectWithTag("CanvasPointers").GetComponent<RectTransform> 
         ().localPosition);

          BlackCursorImage.GetComponent<RectTransform>().localPosition = new Vector3(mousePos.x + 
          15, mousePos.y - 15, mousePos.z);

         }

       else
       
 {

     BlackCursorImage.enabled=false;
     Vector3 mousePos = (Input.mousePosition - 
     GameObject.FindGameObjectWithTag("CanvasPointers").GetComponent<RectTransform> 
      ().localPosition);

     WhiteCursorImage.GetComponent<RectTransform>().localPosition = new Vector3(mousePos.x + 
     15, mousePos.y - 15, mousePos.z);

       }

 }

}

Sending position over the network with IPun Observable in the same script with something like this:

 #region IPunObservable implementation


 public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
   {

   if (stream.IsWriting)
       {
         // We own this player: send the others our data
         stream.SendNext(BlackCursorImage.transform.position);
       }
       else
       {
         // Network player, receive data
         this.BlackCursorImage.transform.position= (Vector3)stream.ReceiveNext();
       }




       if (stream.IsWriting)
         {
           // We own this player: send the others our data
           stream.SendNext(WhiteCursorImage.transform.position);
         }
         else
         {
           // Network player, receive data
           this.WhiteCursorImage.transform.position= (Vector3)stream.ReceiveNext();
         }



     }

I dont' know if its' better way to do this. Anybody could help me? Thanks!
