Hi, I am trying to understand how to do two things here. 1) Take an existing iam instance profile, and get it 2) Attach an existing managed policy to the instance profile

instance_profile = iam.get_instance_profile(name="ab-dev")
policy = iam.get_policy(arn="*:policy/policy_test")
iam.RolePolicyAttachment(role=instance_profile,resource_name="policy_test",policy_arn=policy)

and it seems to be complaining about awaits and async
