SSO for 2 Different Angular Apps

Hi There

I’m building 2 angular applications with SSO feature. How can I enable and test the SSO feature locally?
I would like to login to the first app using okta account and move to the secong angular app by using the same token, ie without prompting the login page.

Can you please help me on the same? It is very critical to me to decide whether we can use okta in our application.
