OBS Virtual Cam to Discord

I'm running OBS 26.0.2 (64bit) on macOS Mojave 10.14.2.
I'm running the latest version of Discord.

The new Start Virtual Camera button hasn't displayed below Start Streaming & Recording, but it has shown up under Tools > Start Virtual Camera. This may have been the OBS-VirtualCam MAC I installed.

My goal is to Livestream a Logic Session onto Discord for my band members. However, when I go onto Discord the OBS Virtual Camera does not display under Video Settings > Camera.

I've been able to successfully use the Virtual Camera on Zoom.

It also works on the Discord Web App.

Would anyone be able to pinpoint what my problem might be? Thanks in advance.
