Gio.SimpleAction

const Gio = imports.gi.Gio;

let simpleAction = new Gio.SimpleAction({
    name: value,
    parameter_type: value,
    state: value,
});
  

A Gio.SimpleAction is the obvious simple implementation of the Gio.Action interface. This is the easiest way to create an action for purposes of adding it to a Gio.SimpleActionGroup.
