La mayoría de los headers estándar están separados por un carácter "guion", también conocido como el "símbolo menos" (`-`).

Pero una variable como `user-agent` es inválida en Python.

Así que, por defecto, `Header` convertirá los caracteres de los nombres de los parámetros de guion bajo (`_`) a guion (`-`) para extraer y documentar los headers.

And copy the output to the variable `SECRET_KEY` (don't use the one in the example).

Create a variable `ALGORITHM` with the algorithm used to sign the JWT token and set it to `"HS256"`.

Create a variable for the expiration of the token.

Define a Pydantic Model that will be used in the token endpoint for the response.
