I think we could just do the below things in a new file at `apps/settings/test/marionette/app/regions/system.js`
```
function SystemApp(client) {
  Base.call(this, client, null, SystemApp.Selectors);
}
module.exports = SystemApp;

SystemApp.Selectors = {
  'actionMenu': 'form[data-z-index-level="action-menu"]'
};

SystemApp.prototype = {
  __proto__: Base.prototype,
  isActionMenuVisiable: function() {
    var actionMenu = null;
    client.switchToFrame();
    actionMenu = this.findElements('actionMenu');
    if (actionMenu && actionMenu.displayed()) {
      return true;
    } else {
      return false;
    }
  }
}
```
