De esa manera, el `APIRouter` original permanecerá sin modificar, por lo que aún podemos compartir ese mismo archivo `app/internal/admin.py` con otros proyectos en la organización.

El resultado es que, en nuestra app, cada una de las *path operations* del módulo `admin` tendrá:

* El prefix `/admin`.
