  Lists all managed policies that are attached to the specified IAM group.

  <p>
  An IAM group can also have inline policies embedded with it. To list the inline policies for a group, use the
  <a>ListGroupPolicies</a> API. For information about policies, see <a
  href="https://docs.aws.amazon.com/IAM/latest/UserGuide/policies-managed-vs-inline.html">Managed Policies and
  Inline Policies</a> in the <i>IAM User Guide</i>.

  <p>
  You can paginate the results using the <code>MaxItems</code> and <code>Marker</code> parameters. You can use the
  <code>PathPrefix</code> 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.
