> This product might work to coordinate between a bunch of sales groups at an expo or something where quick, instant communication is needed

You nailed it.

Initially I was taken in by the novelty of the idea, but when I started seeing features like Recorded Voice, Figma Integrations etc.. I quickly back tracked.

If this works, it would work for a very focussed scenario where instant communication for a short duration/event is required.

Maybe for things like "ship war rooms" for product launches, or during holiday sale event for e-commerce websites?
