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:
