We want to use Auth0 with AWS Cognito. We have already implemented Cognito Authentication Authorization in our system. What I can do to use Auth0?

We have Cognito authentication in our system already. Now we want to use Auth0 and integrate it for our system. So What should I do? We want to combine AWS Cognito and Auth0 with low efforts. Auth0 should be SAML identity provider or OIDC identity provider?
