Network. Send to client server info.

The problem is - server have all myTransform of all players and correctly shows their location. But client have myTransform only of $$anonymous$$s playercontroller. How to pass myTransform of all connected players to client when he connecting 1st time?

 public Transform myTransform;
 
 [Command]
     public void Cmd_SpawnPlayer(GameObject go)
     {
         GameObject playerPref = Instantiate(playerPrefub, new Vector3(10400, 10000, 90), Quaternion.identity) as GameObject;
         NetworkServer.SpawnWithClientAuthority(playerPref, go);
         Rpc_RecievePlayerGameObject(playerPref);
    }
 
 [ClientRpc]
     void Rpc_RecievePlayerGameObject(GameObject player)
     {
         GetComponent<MainCameraScript>().player = player;
         myTransform = player.transform;
     }
