How to use setContextProperty on QQuickWidget to inject JS module in place of QObject (useful for tests)

example.qml

import QtQuick 2

Rectangle {
    width: 400
    height: 200

    Text {
        anchors.centerIn: parent
        text: logic.GetText()
    }

    MouseArea {
        anchors.fill: parent
        onClicked: {
            Qt.quit()
        }
    }
}

logic.cpp

#include "logic.h"

Logic::Logic(QObject * parent)
    : QObject(parent)
{}

Q_INVOKABLE QString Logic::GetText()
{
    return "Click to exit";
}

logic.h

#pragma once

#include <QObject>

class Logic final
    : public QObject
{
    Q_OBJECT
    Q_DISABLE_COPY_MOVE(Logic)

public:
    explicit Logic(QObject * parent);

    Q_INVOKABLE QString GetText();
};

logic.mjs

export function GetText() {
    return "Click to exit";
}
