Toggle dock icon on macos

[Arichy]

I'm developing a macos application. When the app starts, I hope it only show in menu bar, doesn't show in dock. And there is a settings menu item in the menu, a window would appear after clicking the settings menu item. When the window appears, I want the app icon to show in dock. When the window gets closed, I want the app icon to hide in dock.

I've tried app.set_activation_policy(tauri::ActivationPolicy::Accessory)); to hide it when app starts, but I cannot access app in on_system_tray_event and on_window_event. I need to show app icon in dock when the window appears.
