@aws-cdk/aws-cognito-identitypool-alpha: allowUnauthenticatedIdentities still creates IAM role #25470
Description
Describe the bug
Hello!
When creating an IdentityPool that I only want authenticated users to access I set allowUnauthenticatedIdentities to false. However, this still ends up creating an IAM role for unauthenticated users, eventhough I specified I don't need it and it's not required.
Expected Behavior
When setting allowUnauthenticatedIdentities to false, an IAM role for unauthenticated users should not be synthesized.
Current Behavior
When setting allowUnauthenticatedIdentities to false, an IAM role for unauthenticated users is being synthesized.
Reproduction Steps
const stack = new Stack();
const identityPool = new IdentityPool(stack, 'TestIdentityPool');
Possible Solution
Check if allowUnauthenticatedIdentities is false. If so, do not synthesize the unauthenticated IAM role.
