At my work we use Discord to have virtual "desks" (really just audio channels) so people can drop by and chat while you are at your desk. If you're busy or don't wish to be disturbed you can 'lock' your desk to prevent people from joining it (it limits the room size to 1, aka just you).
It really has helped the social factor of moving nearly everyone in the office to remote working. Every department that has adopted the "virtual office" Discord setup loves it over Slack and basically never uses Slack anymore. It's way less awkward to call people, it's easier to not incidentally disturb them when they're busy, during breaks/lunch you can go to the "breakroom" and hang out and chat with everyone else. And it was all very easy to setup and with the Discord server template stuff we can even clone it for each department with very minimal work (renaming channels to that departments' people).
