Implement Multilanguage support in Config.xml variables

I submitted a new app to the Apple store and I have been requested to state why the app has to access to the Location and Camera.

I manage to do using this on the config.xml:

<edit-config file="*-Info.plist" mode="merge" target="NSCameraUsageDescription">

<string>This allow you you take beautiful pictures of what you are giving away.</string>

</edit-config>

The issue is that I do not understand how I can translate this message. I am using the ngx-translate plugin.

Someone can help me out to find out?

Thank you.
