@liminal_andy thank you for responding.
I think there is a learning curve here I have to sit down and dive into. So far I got to the point where I downloaded and installed Zoom OSC and got a solo Zoom session going. What I can't figure out is how to (without vmix) get the Zoom source directly into Izzy without using screen capture.
Ultimately the end result is actually blending the participants together on one screen via Izzy - mixing 2+ sources as cameras (one local, one remote) at minimum.
I've gone through a few Zoom OSC tutorials, and can't seem to find one that does this (and again a learning curve in order to apply information I've learned in the other tutorials just yet).
