Delete your annotation
With the Collaborative Review (CR) feature, you can delete any annotation you added as long as no one else has replied. Once another user replies to your annotation, your annotation is locked and you cannot delete it.
Only the user who added an annotation or reply can delete it. You cannot delete another user's annotations or replies. All replies to an annotation are locked except for the most recent reply to preserve the comment history and content.
To delete your annotation:
Your annotation is deleted from the topic and the Annotations side panel. If it was a reply to another annotation, the other annotation remains.
