List comments
comments, nextCursor, and totalCount. Pass nextCursor as cursor for the next page; it is null on the last page.
Each comment has an id, authorName, body, createdAt, ownedByViewer, deleted, and replies. ownedByViewer is true for the learner you passed, so you can show a delete action.
Post a comment or reply
displayName from your signed-in session, never from the browser. Replies go on top-level comments.
Delete a comment
Limits
Each comment includes at most 50 replies, without a separate cursor. Discussion requests have their own rate limits, separate from launches.
