Why

I needed to integrate react-native-voip-push-notification into an Expo project, but it requires additional native configuration. To simplify this process and make it reusable, I created an Expo config plugin that automatically sets up the necessary changes.

How

• Implemented a custom Expo config plugin.
• Added logic to configure Info.plist and other native settings required by react-native-voip-push-notification.
• Ensured the plugin runs during expo prebuild, so no manual native changes are needed.

Test Plan

• Created a test Expo project with react-native-voip-push-notification.
• Ran expo prebuild and confirmed that the plugin correctly applied the configuration.
• Verified the app builds and receives VoIP push notifications on iOS.
