I have checked Etcher application with Taccy Version 1.11 (20) and it tells me about access to the camera and microphone.
App path: /Applications/balenaEtcher.app
app ID: io.balena.etcher
NSCameraUsageDescription : This app needs access to the camera
NSMicrophoneUsageDescription : This app needs access to the microphone
SDK version: macosx10.15
Could someone clarify why Etcher needs such permissions?
