How do I update a users display name in firebase in Xamarin?

Question

After creating a user in Xamarin using firebase:

await FirebaseAuth.Instance.CreateUserWithEmailAndPasswordAsync(email, password);

I want to update their display name so that when I sign them in I can just get it from what the sign in method returns. I have tried the following but it does not seem to work, What is the right way to do this?

var changeRequest = user.User.ProfileChangeRequest();
changeRequest.DisplayName = username;
await changeRequest.CommitChangesAsync();    
await firebaseUserInfo.UpdateProfileAsync();

You can use following code from SO's thread:https://stackoverflow.com/questions/69645770/how-do-i-update-a-users-display-name-in-firebase-in-xamarin

   var firebaseUserInfo = FirebaseAuth.Instance.CurrentUser;  
               UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder().SetDisplayName(username).Build();  
               await firebaseUserInfo.UpdateProfileAsync(profileUpdates);
