client.isAuthenticated(sessionManager) is only available on PKCE flow. so then, how can i know if the user is authenticated or not, as far as i know, after login() is invoked, it tried to set ac-set-key or acwpf-state-key if using PKCE flow to the session. and isAuthenticated() expect access_token to available in the session. which is i think is not related at all.
