HDMI Video Capture Card support for Virtual Production

Hello all,
Having some continued frustration trying to get my camera into UE.
My rig…
MacBook Pro with dual core i5, 8gb ram, eGPU with Radeon RX850 w/8gb ram
Elgato HD60s capture
Nikon D560, also a Logitech 920 webcam.
I’ve followed a bunch of the tutorials, but can’t get either camera to show up in the video popup selection of the media player.

Any ideas?

I wonder if UE can’t see my cameras because it doesn’t ask for permission for them like other programs?
