Help with Cordova Ionic for iOS app and Apple social Login

We are facing an issue on our Cordova Ionic app where we have implemented apple social login. The app is rejected because the social apple login is not as expected. We cannot get the info from the user when the user tries to sign in and the first name and last name is not prepopulated as it should be from Apple store. The language is Angular

We would like someone to help with this issue but if they want they can also work long term on the project
