I have set up aws cognito and would like to use their federated identities to authenticate users against my own database but on getting a token after calling the get_open_id_token_for_developer_identity() and then calling the get_credentials_for_identity() the response is identityID , AccessKey , clientSecret and session token but this accesskey and client secret do not match the security credentials for my root user or even the IAM users and when used in postman with the AWS SIGNATURE authorization it throws an unauthorized error . I am getting the credentials after calling the get_credentials_for_identity() using identity id and in login{"cognito-identity.amazonaws.com":<token_from_get_open_id>} but the response which includes accesskey and client secret does not let me hit the api now secured using cognito
