Como recuperar uma lista de todas as políticas de um determinado tipo de uma organização

O seguinte exemplo mostra como obter uma lista de SCPs, conforme especificado pelo parâmetro do filtro:

aws organizations list-policies --filter SERVICE_CONTROL_POLICY

A saída inclui uma lista de políticas com informações resumidas:

        "Policies": [
                {
                        "Type": "SERVICE_CONTROL_POLICY",
