Suggestions how to Run 'camera layers' apps on each client and communicate commands between them

Hi,

I want to run my app on each participant in a meeting and then will control look of each video using the camera mode.
However, I also need to be able to send commands from the host to all the participants and receive back data. I could do this through my server, but I wondered if there is an elegant ways
for apps to communicate through Zoom ?

I will want to ‘listen’ to the chat messages. So if there any extra options there?
all the best

p.s. spent all my free time downloading and installing Zoom Apps. Having so much fun and lots of silly ideas now!

Am I the only one that answers my own questions. You need the VideoSdk to get to the chat, so I found a different answer.
