Xcode - Privacy - Camera Usage Description won't ask the permission for the camera - ios

Question

My app developed in Xcode with Objective-C should ask for the camera permission in order to reply to a SIP video call.
Although i wrote the Privacy - Camera Usage Description Key into my info.plist file the app only asks for the microphone permission and not for the camera permission and when I start a video call it crash.
This is my info.plist file:
My info.plist file
Also, If I go to app settings in iOS Settings there is no camera permission switch.
Update with code as requested
To make a video call i use the ABTO VoIP SDK.

The call code is fine, because I tested it multiple times. The issue is that the app does not ask for the camera permission.
