AWS as an OIDC IdP

Hello everyone. I am trying to set up AWS as an OIDC Identity Provider in Keycloak. I think what I am missing is the /.well-known/openid-configuration endpoint. This endpoint should come from AWS right? And what I need to set up in AWS is an OIDC application? Is this correct?

If so, please could someone help me as to where to find the OpenID config endpoint?
