Macro Lens for Webcam Utility

[mherzogny]

I'm using my t6i as a webcam.  I usually use my nifty 50mm lens and it works well.  I recently got the 

Canon EF-S 35mm f/2.8 Macro IS STM 

This one doesn't seem to work as a webcam.  When I connect to Zoom, I get an error trying to show the video.  Has anyone ever used this macro lens and the webcam utility?

Thanks!
