(.NET Core C#) Aruba Fatturazione Elettronica refresh

The token can be renewed by submitting a refresh request, which requires the following parameters in the format application/x-www-form-urlencoded with UTF-8 encoding. Refreshing the token, avoiding sending login details, offers more security and a more efficient process than requesting a new token via signin.
