EmailLinkSignIn - retrieve email used

Is there any way to retrieve the email used to send an email link without implementing a custom function/implementation of the firebaseui react?

i.e. it'd be great to have something similar to the below in the umailLinkSignIn callback:

```
emailLinkSignIn: function(email) {
window.localStorage.setItem('emailForSignIn', email)
}
```
so we can avoid reprompting for the email.
