            For modals opened from Action Bar extensions.
            Depending on the extension point, different parameters are passed to the modal.
            This example illustrates a modal for the AEM Content Fragment Console (list view), where typically a :selection parameter is used to pass in the list of selected Content Fragments.
            Where as Header Menu extensions do not use a selection parameter.
