Get Session ID with responce of Saml application

Hi there!
I need help. In Acumatica ERP I tested OneLogin it works fine but I need to implement octa.
In login page I push button then I successfully authenticate in octa and then I redirected back. I have SAMLResponce,
but my app can’t create session because there is no [sid] variable

I used this tutor: https://developer.okta.com/blog/2017/03/16/spring-boot-saml

The session cookie is seperate from the SAML response: https://developer.okta.com/use_cases/authentication/session_cookie/

In developer tools you should be able to review it under response cookies:
