So I was thinking, with the wifi accessory on the OP, the mic interface accessory doesnt work.
I came across this thing: https://www.amazon.com/Poyiccot-Adapter-Straight-Coupler-Connector/dp/B072PR8Q4S
which is a female to female USB C coupler and it got me thinking..

Would it be possible to connect the mic interface to the usb-c interface on the side of the OP where you normally would conect your phone, using this thing?

Has anyone tried this yet?
And if it works.. would this be a way to connect the "non working" cheaper options from aliexpress etc and see if they work that way?

I thought it was an interesting option to explore, so I decided to share it here, but I am probably not the first one to come up with this idea, i guess?
