I have a multiple AWS account w/ Cognito User Pool and another AWS account w/ Cognito Identity Pool. Is there any way to add those Cognito User Pools to Cognito Identity Pool on another AWS Account? or can I connect them via OpenID, SAML or Custom Protocol?
I'm trying to add AWS_IAM authorization on API Gateway so that all users that are authorized on said User Pool can access the API after logging in on Identity Pool.
Thank you in advance.
