[Firebase-authentication] Saml provider in Identity Platform via Firebase usage for mobile

Current Situation.
We already have a working web app and it uses SAML for authentication.
it is from Microsoft Azure SAML

const provider = new firebase.auth.SAMLAuthProvider('saml.myProvider');
firebase.auth().signInWithPopup(provider)
  .then((result) => {
  })
  .catch((error) => {
    // Handle error.
  });

but we also need to use that firebase authentication in mobile.
how can I access that existing FirebaseUser in mobile?

FirebaseAuth.instance.currentUser.uid

Seems like there is an SAMLAuthProvider but the SDK throws an exception calling signInWithPopup. It looks like there is no way in convertPlatformAuthProvider to convert to a native AuthProvider.

Does any one know if there is a way to work around this?
