Camera with microphone permissions

Am writing an app using JUCE that takes snapshots with Camera from a PC or mobile device, but does not require microphone. OSX XCode asks me to add an info.plist description granting permission for Camera usage. I do this in the Apple recommended way and my app then correctly prompts the user with my description as to why Camera access is needed. The problem is that it then goes on to ask for permission to use the microphone. My code does not try to access the microphone. Is this because on my Macbook the microphone is integral to the camera, or might it be because I have inadvertently included a JUCE component I shouldn’t have, or because maybe I need to set a pre-processor value blocking microphone usage?
