Fix error with React Native and Amplify

My app has been built in React Native using push notifications via AWS Amplify. The app has just undergone an update from @aws-amplify/pushnotification (deprecated) to @aws-amplify/rtn-push-notification. This involved following the migration process here: https://docs.amplify.aws/lib/push-notifications/migrate-from-previous-version/q/platform/react-native/.

After this update calling Analytics.updateEndpoint now results in the error:

InAppMessaging.AWSPinpointProvider - Failed to initialize AWSPinpoint', [Error: Native module not found]

I need this fixed so that the update endpoint works as it perviously was.
