Storybook integration with Expo React Native not working - reactjs

Question

I am trying to get Storybook running on a react native app build by Expo. I generated my project with:
expo init storybook-test
I entered the folder and ran:
npx -p #storybook/cli sb init --type react_native
...which I got from this tutorial and it added multiple files and folders such as:
- Root
- - storybook
- - - stories
- - - addons.js
- - - index.js
- - - rn-addons.js
It then told me to:
add the following to your entrypoint (usually App.js or index.js).
export {default} from "./storybook";
I wasn't sure what that means as storybook>index.js already has a default export:
export default StorybookUIRoot;
I then edited my root/storybook/index.js as there is no main.js in my project to the following:
// if you use expo remove this line
// import { AppRegistry } from 'react-native';
import { getStorybookUI, configure, addDecorator } from '#storybook/react-native';
// import { withKnobs } from '#storybook/addon-knobs';
import './rn-addons';
// enables knobs for all stories
// addDecorator(withKnobs);
// import stories
configure(() => {
require('./stories');
}, module);
// Refer to https://github.com/storybookjs/react-native/tree/master/app/react-native#getstorybookui-options
// To find allowed options for getStorybookUI
const StorybookUIRoot = getStorybookUI({});
// If you are using React Native vanilla and after installation you don't see your app name here, write it manually.
// If you use Expo you should remove this line.
// AppRegistry.registerComponent('%APP_NAME%', () => StorybookUIRoot);
export default StorybookUIRoot;
After all this, I ran yarn storybook and it opened the webpage but the stories never load.
What am I doing wrong?!
