How to handle menu click event?

[Eliot00]

use dioxus::{
    desktop::tao::menu::{MenuBar, MenuItemAttributes},
    prelude::*,
};

fn main() {
    dioxus::desktop::launch_cfg(app, |cfg| {
        let mut root_menu = MenuBar::new();
        let mut settings_menu = MenuBar::new();
        settings_menu.add_item(MenuItemAttributes::new("偏好设置"));
        root_menu.add_submenu("File", true, settings_menu);

        cfg.with_window(|w| w.with_title("Quake").with_menu(root_menu))
    });
}

fn app(cx: Scope) -> Element {
    cx.render(rsx!(
        link { rel: "stylesheet", href: "https://unpkg.com/tailwindcss@^2.0/dist/tailwind.min.css" },
        h1 {
            class: "text-2xl",
            "Welcome"
        }
    ))
}

How to track menu click in dioxus so I can open a configuration window? I found DesktopConfig has a function with_event_handler, how to use it change current window content or create a new window?
