Selection of external USB Audio interfaces on iOS

It would be great to be able to select external USB audio interfaces on iOS devices to be able to connect XLR microphones or line inputs (e. g. for guitar or electric piano) in order to be able to execute remote music lessons in times of Covid-19 (or later). An additional integration of Studio Link for mobile devices such as phones and tablets would be the cherry on the cake.

I have the same question. Did you succeed in setting up a connection with an audio interface?
