I am using the conversation about a cafe to discuss something that I've known for three decades. This is often the case with people. My father can diagnose a bone and joint injury in minutes and often he can guess at history. "What kind of conclusion are you drawing from five minutes of palpation?"
I don't know, as an user I find Slack's thread badly designed. A much better model is Discord's thread as other poster have said. Slack threads are very hard to search and not seems to be designed for 100+ to 1000s messages.
