I'm not sure about that specific application or website, but on Magic Leap 2, when enumerating cameras inside a web application, you'll typically see three options:
- Camera 2.0
- Camera 2.1
- Stream Camera
You can see these options on websites such as Google Meet and others that display available cameras.
To avoid conflicts with the ML2 recorder, I recommend using Camera 2.1. This option won't capture Mixed Reality content but will allow you to record and stream video to your web application without issues.
