I have a wireless mic receiver with Lightning, USB-C, and 3.5mm TRS connectors. I'd like to be able to use this receiver while my iPhone SE is connected to a computer to use the OBS camera app. I've tried two Belkin adapters -- one with a 3.5mm jack and a lightning port and one with a two lightning ports -- and neither works.
I saw this question but it's not clear if that allows for data transfer between the phone and a computer while the audio is being received by the phone.
I found a solution which I will post here for the benefit of others. What is needed is a "Lightning to USB3 Camera Adaptor" which allows USB3 and Lightning devices to be connected simultaneously. So you can use the Apple Charger to power the iPad through the lightning port, and connect other devices via USB3.
Question: How can I achieve iPhone SE audio input simultaneously with computer data transfer?

Copy-paste from the OBS camera web site:
If you've ever wanted to stream using your iPhone camera. We've got you covered. We've tried all the apps that let you do it over wifi, but they weren't fast enough, so we created an app that not only streams video & audio over Wi-Fi, but also over a low-latency wired USB connection to your Mac and PC using our OBS Studio plugin.
Failed Adapters
I used the Belkin adapter with the two lightning connectors (P-F8J198) and the adapter with a lighting connector and the 3.5 mm jack (P-F8J212), but neither allows simultaneous audio input and data transfer. I got ambiguous responses from Belkin's online chat about the capabilities of each device, but neither provided the functionality I want and I will be returning both. The two-lightning-connector version does not support data transfer; the 3.5 mm version dos not support audio input. edit: Subsequently I did try the adapter in the other question; it also doesn't allow a data connection.
What Does Work
Using OBS Wi-Fi kind of works -- the audio is garbled. This happens whether I'm using the built-in mic or the external mic, so it's hopefully not an issue with the mic and the OBS app. There is no garbling when using the built-in mic and OBS over USB. The mic works fine plugged directly into the phone.
