When you
Control (Ctrl) key whilst clicking on the iSight button in the search panel did that panel give you the choice of "
FacTime HD Camera (built-in)"

Onyx from Titanium Software.
ONLY DOWNLOAD THE VERSION FOR YOUR macOSI let it run (Tick all the boxes) ALL the Maintenance tasks EXCEPT Options Bookmark Icons.
There is new LogiTech software available for your webcam:
Software Version: 2.0.200
Last Update: 2020-02-11
OS: macOS 10.15.x, macOS 10.14.x
File Size: 87 MB
But LogiTech is also very compliant with the international UVC (USB video class) software to enable it to run generically on macOS hence why it is working with Skype and FaceTime.
But after carrying out some research some people, software developers etc, have experienced problems with macOS10.14 Mojave and UVC complaint cameras outside of macOS and MS Windows OS. This is one reason to always try and run the latest version of any and all software including Operating Systems.
