Python PyQt6 QtDBus Interface Method Call

Question

I am having trouble calling a method to the D-Bus. Check this code:

class DBusAdaptor(QDBusAbstractAdaptor):
    pyqtClassInfo('D-Bus Interface', 'org.pyqt.LinuxCleaner')
    pyqtClassInfo('D-Bus Path', '/LinuxCleaner')

    def __init__(self, parent):
        super().__init__(parent)
        connect = QDBusConnection.connectToBus(QDBusConnection.BusType.SessionBus, 'LinuxCleaner')
        conn_iface = connect.interface()
        if not connect.registerService('org.pyqt.LinuxCleaner'):
            print('Failed to register service')
        if not connect.registerObject('/LinuxCleaner', self):
            print('Failed to register Object!')
        print(connect.baseService())
        self._check_polkit_privilege(conn_iface, 'org.pyqt.LinuxCleaner')

    def _check_polkit_privilege(self, conn_iface, service):
        """
        :param conn_iface: D-Bus connection interface.
        :type conn_iface: QDBusConnectionInterface
        :param service: D-Bus service name.
        :type service: str
        :return:
        """
        pid = conn_iface.servicePid(service).value()
        interface = QDBusInterface('org.freedesktop.PolicyKit1',
                                   '/org/freedesktop/PolicyKit1/Authority',
                                   'org.freedesktop.PolicyKit1.Authority',
                                   QDBusConnection.systemBus())
        struct = QDBusArgument()
        struct.beginStructure()
        struct.add('unix-process', 10)
        struct.beginMap(10, 3)
        struct.beginMapEntry()
        struct.add('pid', 10)
        struct.add(pid, 3)
        struct.endMapEntry()
        struct.beginMapEntry()
        struct.add('start-time', 10)
        struct.add(0, 3)
        struct.endMapEntry()
        struct.endMap()
        struct.endStructure()
        struct.add('org.pyqt.LinuxCleaner.auth', 10)
        struct.beginMap(10, 10)
        struct.beginMapEntry()
        struct.add('AllowUserInteraction', 10)
        struct.add('true', 10)
        struct.endMapEntry()
        struct.endMap()
        struct.add(1, 3)
        struct.add('', 10)
        reply = interface.call('CheckAuthorization', struct)
        print(reply.errorMessage())

I get the following error message: Type of message, “((sa{su}))”, does not match expected type “((sa{sv})sa{ss}us)” I take that to mean that {sv} requires a QDBusVariant (according to Qt docs), yet beginMap() only accepts QMetaType's as arguments. QDBusVariant is not an exposed Meta Type. How would I solve this? How can I pass a QDBusVariant to beginMap()? I can't, can I?
