Powerpoint Office 365 - VCam not showing up as CAM?

Hi Folks,
When I attempt to do a recording in PPT, it defaults to the Logitech Device and does not list VCAM as an option (like many other programs). Is there a setting that I am missing in Windows or Office 365 to default to VCAM as the Camera of Choice?

Thanks

I have the same problem. Hoping someone can help with this!
