There is no camera button on desktop

I'm trying to do an integration and testing on desktop I cannot get past the first image capture.

My camera is a 1080p logitech webcam, works great for zoom, google meets, etc.

Before I hold up the card for the first time, it's telling me to move my card back. Then after I hold up my card, it tells me to put the card on a non-reflective surface and frame it in the rectangle, which makes sense for mobile. But I'm on desktop... I'm holding up the card.

Eventually I get "if you're having trouble taking a picture, use the camera button instead", which ends up pretty frustrating because there is no camera button... :)
