javascript
const annotationManager = docViewer.getAnnotationManager()
const annotationsList = annotationManager.getAnnotationsList()
docViewer.showAnotations(annotationsList)

Hide Annotations ​

You can use the hideAnnotations method of the annotationManager to hide annotations.

javascript
const annotationManager = docViewer.getAnnotationManager()
const annotationsList = annotationManager.getAnnotationsList()
docViewer.hideAnotations(annotationsList)
