Brand new user - trying to figure out MIDI Guitar 2

I have only classical guitars. I have microphones. I was trying to use the standalone version of MIDI Guitar 2 trial but the audio interface does not recognize my microphone. It shows some stuff like Focusrite USB, Voicemeeter which I probably have in my list of devices but I want to use my Shure MV51 Microphone as the input device.

Does it not support all hardware? shure mic is a usb mic.
