AI Assistant showing track changes

I have seen one of  's examples of the AI Assitant window (originally in this post: community.rws.com/.../171506) showing track changes (Odonates varieties). I was wondering if this is a specific prompt option (if so, what string did you use?) or if this was a default system setting of the OpenAI provider Plugin of that version (in my today's version 1.2.10.0 track changes are not shown). 
Thank you.
