I answered a question yesterday that ended up in the HNQ. There were a few reasonable comments on my answer, then a side-discussion popped up about dealers and ethics. I flagged those comments as no longer needed, but my flags were declined. Another moderator saw the conversation and moved it to chat (this was my desired outcome; fewer notifications on my cellphone app for an argument that didn't interest me). I don't think it would have been a problem to delete the comments entirely, but moving it to chat was fine too.
What should I do differently to achieve this result the first time I flag so that my flags are not declined?
