Specifying Settings for IAM Role
[This step applies if you selected the IAM role from the current account option]
At the Role Settings step of the wizard, specify the name of the IAM role that you want to add. You must specify the name that the IAM role has in AWS.
If there is a path identifying the IAM role, you must specify the role name in the PATH/NAME format (for example, dept_1/s3_role). To learn how to add identifiers to IAM roles, see AWS Documentation.
