In my team we treat slack exactly like an open office. So each day/week we choose a volunteer to handle slack for us, and if needed they can pull on the other team mates but in general we try to preserve a deep work flow for all the other members than the one on slack/support duty. There are also no expectations that the one on support duty does their normal work during this time. Instead we choose to do devrel work , like outreach, polish documentation and such. We are a platform engineering team so this approach might not be possible for others but it has probably been the best thing mentally since the start of working remotely.
