Just wanted to thank you for sharing your code! Worked great!

Some related things in case anyone else walks down this road:

- be sure to add your domain to Authorized domains in Firebase Console (Authentication → Sign-in Method)

- pay careful attention to this comment in the code above, during testing it might catch you off guard `// In this case, we are enforcing that the user signed in in the last 5 minutes.`

- if you need to use CORS to access from a different domain you can use multiple middlewares by passing in an array: [cors(corsOptions),formidable()]

Thanks again for sharing!
