When authenticated users visit the main site (www.domain.com), we would like to be able to detect them as authenticated, so that we can retrieve their Auth0 profile information for the purposes of personalizing the UI (e.g. reflecting their logged in status in the navigation) and identifying them in analytics (e.g. Google Analytics tracking calls).
Are there any guides or suggestions on the approach to get this working? Any guidance is really appreciated, since I don’t know where to begin.
