How do I hide app ICONS on the taskbar

[tgy3300]

I want to implement hidden app ICONS on the taskbar, according to
https://github.com/slint-ui/slint/issues/4341
It still can't happen

----index.slint----

export component MainWindow inherits Window {
    ...
}

----main.rs----

let main = MainWindow::new().unwrap();
main.window().with_winit_window(|winit_win| {
	winit_win.set_skip_taskbar(true);
});

What's wrong

What kind of error do you get?

What kind of error do you get?
no method named with_winit_window found for reference &Window in the current scope
items from traits can only be used if the trait is in scope

Is there no way to make it happen

This is private API.
You need to do use i_slint_backend_winit::WinitWindowAccessor
