[Angular Web Portal] - How to retrieve logged user's Central Account

How can I retrieve logged user's Central Account?

In session I can retrieve userId, isLoggedIn and Username parameter, but no one of these is identity Central Account.

this.onSessionResponse = this.authentication.onSessionResponse.subscribe(async (sessionState: ISessionState) => {
      console.log("sessionState.UserUid",sessionState.UserUid);
      console.log("sessionState.IsLoggedIn",sessionState.IsLoggedIn);
      console.log("sessionState.Username",sessionState.Username);
      console.log("sessionState",sessionState)
    });

Any suggestion?
