Using Hypno with OBS

Issue getting video… sorry, but I’m new at this.

Mac Mini M1, connected to Hypno via micro USB. Hypno is powered on.
OBS 26.1.2 (64-bit)
obs-ndi-4.9.0
NDI 4.5.1 macOS runtime

I followed the instructions on this post to resolve known issues with NDI as a source in OBS with M1 macs:

I followed your Youtube tutorial “Hypno with OBS”.

I am able to select Hypno (main) under the NDI sources/Source name but I can’t see any video output . What am I doing wrong??
