Nikon Z5 Tether Problem

I can't get LightRoom Classic (current version 10.0) to see my camera when I try to tether. I am using the USB cable that came with the camera, and I've even tried connecting the camera to the iMac computer using this short cable without an extension. LightRoom just says that it can't find the camera. I've tried calling Adobe Customer Care but everytime after 20 minutes I'm either disconnected due to the incredibly poor connection or the music stops and I'm left in limbo forever until I finally give up. Finally, with regard to lenses, I don't think this matters as it's not seeing the camera, but I have 3rd party lenses that do work now with the recent update of LightRoom to 10.0.
