Should this use similar approach as in https://codereview.chromium.org/253463002
instead?

OAuth2LoginManager code is not executed for kiosk. It is be better just do
InitChromeOSPreferences.

   kiosk_profile_loader_.reset();
   startup_app_launcher_.reset(
       new StartupAppLauncher(profile_, app_id_, diagnostic_mode_, this));
