1. What will be CallbackURL and Logout URL at AWS end.
2. Request your help to provide additional details on Step #4, #5 and #6 of filling the form in the Connector as it is not much clearer how to configure.
Both URL should be your own application URL. Callback URL is the URL where Cognito should redirect to after authentication and logout URL is when Cognito log off where it reditect to log out. Example:
https://<your app url>/redirect_ url
https://<your app url>/logout
Hope this helps
