App freezes when calling prefetchConfiguration with no internet connection

Issue

When calling prefetchConfiguration with device in airplane mode or with no internet connection the app freezes.

This is the error I get: E/AppAuth: Network error when retrieving discovery document.

config.js file

import { prefetchConfiguration } from 'react-native-app-auth';

const config = {
  warmAndPrefetchChrome: true,
  issuer: 'https://login.microsoftonline.com/1caa43b8-bf09-48b6-9b3c-bd5a56fec019',
  clientId: '5e0b7c9c-aaaa-472a-8ec6-6362c6d56fbe',
  redirectUrl: 'msauth.com.rccl.oauth://auth/',
  additionalParameters: {},
  scopes: ['openid', 'profile', 'email', 'offline_access'],
};

prefetchConfiguration(config);

export default config;

Also tried using try/catch, still the app freezes.

try{
prefetchConfiguration(config);
}catch (error) {
  console.log(error);
}

any fix ?

I think in general we should check on the React Native side whether the app is connected to the internet before triggering this request, since none of the methods would work with no internet... but it's probably sensible to have a fallback, so we could add a timeout to the request.
