The lockdown can be + * removed by right clicking the button - the user can discover this + * through the tooltip. If the Authority implementation does not + * support lockdown, the widget will be hidden. + * + * Finally, if the user is not authorized but authorization can be + * obtained and the obtained authorization will be a one-shot + * authorization, the widget will be hidden.
