Is it possible to show a web page hosted on the Internet in a plugin dialog ?

Sorry, I was sure that I tried both of them (WebView and WebEngineView) and get similar error in the both cases but I tried again and it works. For instance, this works (I run it successfully on Windows 10 laptop):

import QtQuick 2.0
import QtWebEngine 1.4
import MuseScore 3.0

MuseScore {
menuPath: "Plugins.pluginName"
description: "Description goes here"
version: "3.0"
pluginType: "dialog"
width: 500
height: 500

  WebEngineView{
     id : webEnginView
     width: 500
     height: 500
     url : "http://www.google.com";
  } 

  onRun: {
        console.log("hello world")
  } 

}
