How to use the ipyvuetify.ListItemAction function in ipyvuetify

def __init__(self, session=None, output_widget=None):

        self.output = output_widget
        self.session = session

        self.modes = [
            ("replace", icon_replace, ReplaceMode),
            ("add", icon_or, OrMode),
            ("and", icon_and, AndMode),
            ("xor", icon_xor, XorMode),
            ("remove", icon_andnot, AndNotMode),
        ]

        items = []
        for mode in self.modes:
            item = v.ListItem(children=[v.ListItemAction(children=[mode[1]]),
                                        v.ListItemTitle(children=[mode[0]])])
            items.append(item)

        for item in items:
            item.on_event('click', self._sync_state_from_ui)

        mylist = v.List(children=items)

        self.main = v.Btn(icon=True,
                          children=[self.modes[0][1]], v_on="menu.on")

        super().__init__(
            v_slots=[{
                'name': 'activator',
                'variable': 'menu',
                'children': self.main
