reply-to-comment
Add a reply to an existing comment thread on a design.
Use reply-to-comment to answer a reviewer's question, acknowledge or clarify feedback, or continue a discussion on a specific comment. The reply is visible to everyone with access to the design. To start a new thread instead, use comment-on-design.
Example prompt
"Reply to Sam's comment on the launch deck and let them know the pricing is updated."
Pass the design_id, the comment_id of the thread to reply to (from list-comments), and the message_plaintext (1 to 2,048 characters).
Example response
IDs below are placeholders; field names and structure are exactly as returned.

JSON
The new reply has its own id, and its thread_id matches the comment_id you passed. The reply text is in content.plaintext.
