Beachten Sie, dass wir async/await mit dem neuen `AsyncClient` verwenden – der Request ist asynchron.

/// warning | "Achtung"

Falls Ihre Anwendung auf Lifespan-Events angewiesen ist, der `AsyncClient` löst diese Events nicht aus. Um sicherzustellen, dass sie ausgelöst werden, verwenden Sie `LifespanManager` von <a href="https://github.com/florimondmanca/asgi-lifespan#usage" class="external-link" target="_blank">florimondmanca/asgi-lifespan</a>.
