guest chat without joining team
We have a team made of people who know things about a certain topic. Other people who are not part of our team want to talk to us (for example to ask us questions about that topic).
Teams should give those people a way to talk to us without joining our team.We've made the Team public so anyone can join, but having to join the team at all (and then leave the team when they're done talking to us) isn't the right experience.
The way this would work in my head is the permissions for a channel would have a section labelled "anyone in the organisation" and it would have setting for "can post messages".
