Question about remote control across network

I run two instances of Mimo on 2 different machines on my local network (small zoom pin farm).

I want to make a single remote control panel to trigger file recordings for the 2 docs.

It does not seem possible to add remote control command from Mac B into a remote surface on Mac A.

Not sure if this needs to be done with Automation layer or something else.

I did get remote show start from Mac B to work via streamdeck button attached to Mac A using automation layer and streamdeck mimo layer command. Could not get this to work with local document on Mac A for some reason.

What is the best approach?
