We are still using the same `OAuth2PasswordRequestForm`. It includes a property `scopes` with a `list` of `str`, with each scope it received in the request.

And we return the scopes as part of the JWT token.

!!! danger
    For simplicity, here we are just adding the scopes received directly to the token.
