Auth0 integration with WinForms application

Hi,
I am created one application in WinForms with auth0 (SSO is enabled) integration. I have some question regarding that.

  1. It is possible to check if user already logged in or not without calling “LoginAsync()” function?
  2. How to control property of the Window which open using “LoginAsync()”? ( Property like StartPosition, icon, title etc.)

Thanks,
