```js
import auth, { firebase } from '@react-native-firebase/auth';
import firebase from '@react-native-firebase/app';
import auth from '@react-native-firebase/auth';
// create secondary app as described above
const secondaryApp = await firebase.initalizeApp(credentials, config);
// Example using auth with passing the secondary app instance
auth(secondaryApp).currentUser;
```
