I need the ability to disable the "FullScreen mode" button in the window header bar

Since I only want to have a fixed-shaped window, I am using it with the resizable option set to false.

    iced::application("musica", MainApp::update, MainApp::view)
        .settings(setting)
        .window(window_setting)
        .resizable(false)

However, although this prevents resizing by dragging, there is no way to prevent the “full screen button”.

As far as I know there is no function in iced to control this. Do you have any? If not, I would like to request that the feature be added.
