Under this answer:

are two comments:
Comments are not for extended discussion; this conversation has been moved to chat. If there are elements in moved comments and subsequent chat that belong in this answer, then such elements should be edited into this answer not left as ephemera.
and
ᴍᴏᴅᴇʀᴀᴛᴏʀ ɴᴏᴛᴇ: Comments cannot be moved to chat a second time. Please use this posting’s chatroom for discussion. Further comments here will be deleted.
Which seems to suggest that the chatroom is the place for posting any further comments.
Is that how this works?
