I'm not affiliated, just someone who recently started using it daily, but another "always on" video conference alternative is https://tandem.chat/ . It integrates well with Slack, and keeping it open while working with colleagues feels very natural.

It's the closest I've seen to recreate a coworking environment -- we even have a #lunch channel where we "eat together" at noon (that was a bit depressing to write... we're doing what we can to keep up the illusion of normalcy).
