title: How to setup sendSignInLinkToEmail() from Firebase in react-native?
body: <p>Working on a <code>react-native</code> project using <code>@react-native-firebase/app</code> <strong>v6</strong> we recently integrated signing in with a "magic link" using <a href="https://rnfirebase.io/reference/auth#sendSignInLinkToEmail" rel="noreferrer">auth.sendSignInLinkToEmail</a></p>
  
  <p>We couldn't find a good example on how to setup everything in react-native and had different problems like
  - <code>auth/invalid-dynamic-link-domain</code> - The provided dynamic link domain is not configured or authorized for the current project.
  - <code>auth/unauthorized-continue-uri</code> - Domain not whitelisted by project</p>
  
  <p>Searching for information and implementing the "magic link login" I've prepared a guide on how to have this setup in react-native</p>
