/**
* The narrow sidebar UI for displaying annotations.

*
* After selecting an annotation the {@link module:ui/panel/balloon/balloonpanelview~BalloonPanelView} with an
* {@link module:comments/annotations/view/annotationview~AnnotationView} appears attached to the sidebar item.
*
* This UI is intended for medium-sized viewports.
*
* To activate this UI use one of the following:
*
* ```ts
* editor.plugins.get( 'AnnotationsUIs' ).switchTo( 'narrowSidebar' );
* editor.plugins.get( 'AnnotationsUIs' ).activate( 'narrowSidebar', filter );
* ```
*
