Is there a reason OP can't get themselves a $50 USB capture card and a $20 HDMI cable, and use OBS to capture the feed from the HDMI-out in the camera? Most decent capture cards also expose themselves as cameras to almost all applications. This is my setup, and it works perfectly. Nikon D7500 as a webcam. More professional setups use Atomos monitors with built-in NVMe drives mounted directly to the camera.
I generally find the camera manufacturers' in-house programs absolutely terrible. Nikon's webcam utility is free[1], but has significant limitations over the capture card setup. Likewise for Sony. Both have considerable resolution and framerate limits, and I'd rather feed a 4K 60 FPS stream into my meeting program and let it handle the compression than have an XGA 1024×768 15 FPS output from the camera.
