Mediators Need a Knock or Announce Feature!

[fmas]

I've been using ZOOM (on my MAC) since 2020 as do mediators all over the world... HOWEVER, we do not have access to one very important feature that seems like it would be simple for Zoom to offer: a knock or announce feature that we could use before entering the private caucus rooms of our clients and their attorneys. I go back and forth among rooms all day long and I would like a simple button to push, something that audibly sounds, similar to a knock or door bell that rings before I put myself into my client's room. Sending a message via chat does not work because the participants are not always looking at their screens. How hard could it be for ZOOM to incorporate this feature?
