Der Name des Formularfelds lautet `scope` (im Singular), tatsächlich handelt es sich jedoch um einen langen String mit durch Leerzeichen getrennten „Scopes“.

Jeder „Scope“ ist nur ein String (ohne Leerzeichen).

Diese werden normalerweise verwendet, um bestimmte Sicherheitsberechtigungen zu deklarieren, zum Beispiel:

* `users:read` oder `users:write` sind gängige Beispiele.

Wir können das alles deklarieren, ohne den ursprünglichen `APIRouter` ändern zu müssen, indem wir diese Parameter an `app.include_router()` übergeben:

```Python hl_lines="14-17" title="app/main.py"
{!../../../docs_src/bigger_applications/app/main.py!}
