AWs SSO with Amplify UI

Hi

I see in the documentation that Amplify UI Authenticator allow other login sources like Google or Facebook, but ¿not allow AWS SSO? I have a setup with cognito + AWS SOO as SAML identity provider.

I log-in using the Cognito Hosted UI, but when it come back to the callback URL the Amplify UI Authenticator not detect the user as logged.

I'm doing something wrong or just Amplify UI Authenticator not support SAML identity providers?
