How to tell the post author’s reply
The badge on the card does not mark comments. The author is the id of the person who published. Their reply in the “how much” thread means that lead was already seen.
For the queue
The queue use-case sets aside threads with the author id. This article is why the match is on id, not the handle on the card.
Frequently asked questions

Then it is someone else’s line: the id will not match. A collab still shows one author on the card.
