if I understood it right, to use FileDialog I must add

QT +=widgets

also https://doc.qt.io/qt-5/qml-qt-labs-platform-filedialog.html needs
widgets and QApplication <https://doc.qt.io/qt-5/qapplication.html>
instead of QGuiApplication <https://doc.qt.io/qt-5/qguiapplication.html>.

want to avoid this because my mobile apps are using QtQuickControls2 only

in forum I read that this URL works from C++ but not from QML
