Agora, todas as requisições sob o path `/v1/` serão manipuladas pela aplicação Flask.

E o resto será manipulado pelo **FastAPI**.

Se você rodar a aplicação e ir até <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a>, você verá o retorno do Flask:

Hello, World from Flask!
