Ah right! When login in that happens, I kept thinking about creating a user, which after OAuth2 comes a user creation dialogs shows up. I guess I want the SSO flow as ideally, the user should not need to create an account again.
I will need to see what can I do. Auth0, the identity provider I use, does not seem to have a clear path to hook up SSO in a straightforward way.
Thanks again, again
