title: React Native - Firebase Microsoft Authentication - Error: `new OAuthProvider()` is not supported on the native Firebase SDKs
body: <p>I'm trying to add a microsoft login to my react native app with the help of firebase. I have done all the preconfiguration in both azure portal and firebase. The issue seems to be with the error (see title).</p>
  <p>I'm following this guide : <a href="https://firebase.google.com/docs/auth/web/microsoft-oauth#web-version-9" rel="nofollow noreferrer">https://firebase.google.com/docs/auth/web/microsoft-oauth#web-version-9</a></p>
  <p>And once i try to create an instance of OauthProvider, i get the error. Here's the specific code (also found in the guide) :</p>
  <pre><code>const provider = new firebase.auth.OAuthProvider('microsoft.com');
  </code></pre>
  <p>Ive looked around and i think there's a couple of hacks for others login such as facebook but i didnt find anything for microsoft yet. It also seems to be the simplier way to implement a login to microsoft button. Simply put, im literally stuck at the first step so if there's an alternative or a way to fix that real quick, i'd appreciate it. Thanks !</p>
