Microphone connects with audio interface but not with audacity

I am on a windows 10 desktop using version 3.0.2 of audacity (cause I like the ui better and it shouldn’t affect this really). I have a Behringer UMC404HD audio interface plugged into the back side of my computer and I have a MXL Cr21 microphone plugged into that.
I can hear myself in the headphones connected to the interface when I make noise on the mic but when I try to record anything in audacity nothing shows up . I’ve tried everything I can think of and nothing shows up online so I don’t know what to do at this point.

You have to tell Audacity to record from the Behringer USB device …
