pub fn app_icon<M>(app_id: impl Into<String>) -> Node<M>Expand description
An application’s icon, found by its app id or window class (firefox, org.gnome.Nautilus)
in the user’s icon theme. Sized like an icon, in the app’s own colors: a tone only dims it.
Until the host has found it, or if there is none, it shows the id’s first letter.
