Limit auth to a certain domain

[pietrop]

👋
I want to limit auth for users from a certain domain eg @example.com.

I've seen that I can setup rules in firestore (eg stackoverflowHow do I create firestore rules based on users email domain?) which is great.

But I was wondering if there was a way to use setCustomParameters( as described here Firebase limit access to certain domains ) in firebaseui-web-react?

var provider = new firebase.auth.GoogleAuthProvider();
provider.setCustomParameters({
    hd: "example.com"
});

I found you can use OAuthSignInOption.customParamter.
Here is example.

  const uiConfig: firebaseui.auth.Config = {
    signInFlow: 'popup',
    signInSuccessUrl: '/',
    signInOptions: [
      {
        provider: firebase.auth.GoogleAuthProvider.PROVIDER_ID,
        customParameters: {
          hd: 'example.com',
        },
      },
    ],
  };
