 A small snippet to add your own copy method, in case the original one has been tampered with.
 
 ```
-document.onkeyup = function(e) {
+var frames = document.getElementsByTagName("iframe");
+let copyFunction = function(e) {
     if (e.ctrlKey && e.which == 67) {
-        var text = window.getSelection().toString()
+        var text = this.window.getSelection().toString()
         navigator.clipboard.writeText(text)
     }
 }
+document.onkeyup = copyFunction
+for (let i = 0; i < frames.length; ++i) {
+    if (frames[i].id == 'mcas-presence-frame-do-not-remove') {
+        frames[i].parentNode.removeChild(frames[i])
+    } else {
+        frames[i].contentWindow.onkeyup = copyFunction
+    }
+}
 ```
