Logout not directing to auth provider

[shawndewet]

Thanks for a great library!
I have configured it for use with AWS Cognito, and the login process works great. When I log in, the redirect to Cognito works, and the logged-in user is redirected back to the /secure page.

When I go back to the home page, it shows as logged in. And I click the Logout button. That is where I get confused. It executes the logout process, and the cookies are cleared. However, it then just redirects back to "/". Where do I configure the process to redirect to the "/logout" url of AWS Cognito. Because without that, the browser is still logged in to Cognito.

Please advise.
Thanks,
--Shawn.
