Getting user profile details from google logging using html api

I am trying to get the user details like email and name using Google login using the new HTML API.

I have been able to make the login work but I am not able to get the user details as I do not know the field names and the syntax to get those details

The login code that I was able to get using the following link:(Identity services for web)

Any help would be hugely appreciated

The generated code sample is:

<script src="https://accounts.google.com/gsi/client" async></script>
<div id="g_id_onload"
     data-client_id="your client id.apps.googleusercontent.com"
     data-context="signin"
     data-ux_mode="popup"
     data-login_uri="http://localhost"
     data-auto_prompt="false">
</div>

<div class="g_id_signin"
     data-type="standard"
     data-shape="rectangular"
     data-theme="outline"
     data-text="signin_with"
     data-size="large"
     data-logo_alignment="left">
</div>
