Auth0 Lock in React app not catching ‘authenticated’ event with SSO conection type

I have React SPA and use auth0 lock. I need to know when the user logged in and save it to DB. When the connection type is Database (login/password) I can catch an ‘authenticated’ event and do my staff. But how to do that with SSO connection type. ‘Authenticated’ event is not caught. How my SPA can recognize exactly login, not page refresh?
