Connecting my USB microphone

Hi, I am using MacOS Big ur 11.3.1 and Audacity 3.0.2.
I have a Ansinna M858 USB microphone -
I am new to Audacity.
I have set up the microphone on the Apple preferences but am having difficulty finding it on Audacity. Any suggestions please?

Connect the microphone and verify it through System Preferences > Sound > Input (which it seems you’ve done).

Then start Audacity.

Click on the Recording Device dropdown in the Device toolbar. Do you see your microphone listed there?
