-- Lists all managed policies that are attached to the specified IAM group.
--
-- An IAM group can also have inline policies embedded with it. To list the
-- inline policies for a group, use ListGroupPolicies. For information
-- about policies, see
-- <https://docs.aws.amazon.com/IAM/latest/UserGuide/policies-managed-vs-inline.html Managed policies and inline policies>
-- in the /IAM User Guide/.
--
-- You can paginate the results using the @MaxItems@ and @Marker@
-- parameters. You can use the @PathPrefix@ parameter to limit the list of
-- policies to only those matching the specified path prefix. If there are
-- no policies attached to the specified group (or none that match the
-- specified path prefix), the operation returns an empty list.
--
-- This operation returns paginated results.
