Respeaker not working with GarageBand or Audacity

Just received ReSpeaker V2.0. Tried on MacOS 10.15.5 with GarageBand 10.3.5. ReSpeaker can be selected in Preferences but when recording it doesn’t work as an input (Error: No input source select). Tried Win 7 Audacity 3.1.1 and it records but the input level is way too high even with the Recording Volume set to 0.0. I tried both of these apps with the built-in mics and they both work as expected.
The ReSpeaker ringLEDs are showing that it’s following my voice.

What is the Garage Band equivalent for Windows?
