For every use case you need a virtual device (in analogy to real hardware: a speaker which outputs zoom, a speaker which outputs mimo)
mimo2zoom (output to zoom - mix-minus zoom audio) and
zoom2mimo (output to mimo)
Just generate another virtual device, With different naming. As described there: How to use BlackHole instead of Loopback (free alternative)
mimo2zoom is the microphone input in zoom.
zoom2mimo is the microphone input in mimoLive.
