Ultrastudio Recorder 3G not sending audio to Zoom

I have an Ultrastudio Recorder 3G, that I'd want to use as a webcam input to my Zoom on a Macbook Pro M1 Pro. Zoom is on the latest version.
I have no issues with a video feed, but there is no audio, even though Blackmagic Ultrastudio Recorder 3G is selected as a microphone. Only when I launch Blackmagic Media Express, will the audio kick in.
I really don't think that this is the correct workflow. How can I get audio and video working without having to run Media Express? Thanks!
