      encapsulation: ViewEncapsulation.None,
      providers: [ToolbarService]
export class AppComponent {
    public container: DocumentEditorContainerComponent;

    public protectDocument(): void {
        //enforce protection
        container.documentEditor.editor.enforceProtection('123', 'CommentsOnly');
