I think what you want is a mobile "audio interface" that is wired to the mobile over usbc, but then this dongle has a Bluetooth chip in and a 3.5mm jack for the lav mic.

So the phone looks like the dongle is doing the audio and then it's split from there.

I know wires are not cool but It's probably easier to do.

This is exactly what you are looking for except with wire:
