Best way to display a customized message to each meeting participant?

Hi all!

I’m new to the Zoom development tools and I’m wondering what the best way to display a customized message to each meeting participant is. I’d like to somehow periodically display customized messages (e.g. a different message per user) to meeting participants throughout a meeting with a Zoom app that is installed on the hosts account. Is this possible? I’d like these messages to ideally to pop as a window, but they could also just simply be a direct message from the host’s app to each meeting participant as well. I also would like them to show up in breakout rooms.

Could anyone provide any direction about what could work?

Thanks,
Elliot
