How to Map Camera Controls (Iris, gain, etc.) to Stream Deck

Hello everyone,
I am a user of the ATEM 1 M/E Production Studio 4K and 3 x URSA Broadcast G2 cameras with Fujinon 20x lenses. I am trying to map some camera control actions, such as adjusting iris (open/close), color temperature, or gain, to a Stream Deck+ using Companion, but I haven't been able to make it work. Has anyone managed to do this?
Thank you!
