- we were already
- statically declaring "NSCameraUsageDescription" in the Info.plist
- this used to be enough in the past
- codesigning with an entitlements.plist that declares "com.apple.security.device.camera"
- I believe this is required for notarization to pass for an app that declares "NSCameraUsageDescription".
- previously this was enough to access the camera IIRC
- in any case, if the user goes into "System Preferences">"Security & Privacy", they can manually modify permissions there
- now with this commit, we on-demand trigger at runtime the OS permission prompt
- making it much easier for users to actually use the camera
- note: if you run via the Terminal, e.g. `$ $HOME/Desktop/Electrum.app/Contents/MacOS/run_electrum`,
then it will be the Terminal app that requires the camera permission. If you run by double-clicking Electrum.app,
then Electrum.app will be the "app" that requires the camera permission.
- `$ tccutil reset Camera` can be used to clear permissions for all apps (back to the Qt::PermissionStatus::Undetermined state)
