-- Lists the names of the inline policies that are embedded in the
-- specified IAM group.
--
-- An IAM group can also have managed policies attached to it. To list the
-- managed policies that are attached to a group, use
-- ListAttachedGroupPolicies. For more 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. If there are no inline policies embedded with the specified
-- group, the operation returns an empty list.
--
-- This operation returns paginated results.
