If the camera permissions are not granted they are asked automatically in Qt 6.5.1 on the first run. There is a popup asking to give permissions and the user simply selects "Yes" to give them.

However in Qt 6.6.1, it's not asked and "Camera access was not granted" log appears in the logcat. There's no indication of a lack of permission in the app, so it's a bit confusing. User should manually go to the app settings, enable the camera permission, and restart the app.
