Hi,

Could you please elaborate what you are trying to implement?

If you want to get a certain type of annotation, you could do so by getting all annotations first and then filter through them like this:

const { annotationManager, Annotations } = instance.Core
const underlineAnnotations =  annotationManager.getAnnotationsList().filter(annot=>annot instanceof Annotations.TextUnderlineAnnotation)

If you want to assign the annotations with an author name, you could loop through the annotations and change the Author property:

underlineAnnotations.forEach(annot=>annot.Author = "Author 1")
