We have have an existing application and we are developing the new APIs required for our application in AWS.
We want to enable role based access control to our AWS API without migrating our users to AWS Cognito. We think we might need to use Developer Identity Provider and IAM Roles, but not sure how the users from our application will be attached to IAM Roles. Any help in this direction will be appreciable.
Thanks in advance.
Note: I am new to AWS.
