We can also add *path operations* directly to the `FastAPI` app.

Here we do it... just to show that we can 🤷:

    // we make a copy here, instead of creating a view of it.

    // TreeMap.navigatbleKeySet().

Para manter as coisas simples, aqui nós estamos apenas adicionando os escopos recebidos diretamente ao token.

Porém em sua aplicação, por segurança, você deve garantir que você apenas adiciona os escopos que o usuário possui permissão de fato, ou aqueles que você predefiniu.
