executionRoleName

The name of the IAM execution role to use to create the stack set. If you do not specify an execution role, CloudFormation uses the AWSCloudFormationStackSetExecutionRole role for the stack set operation.

Specify an IAM role only if you are using customized execution roles to control which stack resources users and groups can include in their stack sets.

Valid only if the permissions model is SELF_MANAGED.
