int main()

    qmlRegisterType<Example>("io.me.qmlmodule", 1, 0, "Example");
    QCoro::Qml::registerTypes();
    ...
}

class Example : public QObject
{
    Q_OBJECT

    ...

public:
    Q_INVOKABLE QCoro::QmlTask fetchValue(const QString &name) const
    {
        return database->fetchValue(name);
        // Returns QCoro::Task<QString>
    }
}

Example {
    Component.onCompleted: {
        fetchValue("key").then((result) => console.log("Result", result))
    }
