-Check out the [Function calling sample](https://github.com/marcominerva/ChatGptNet/blob/master/samples/ChatGptFunctionCallingConsole/Application.cs#L18) for a complete implementation of this workflow.
+Finally, you need to resend the original message to the chat completion API, so that the model can continue the conversation taking into account the function call response. Check out the [Function calling sample](https://github.com/marcominerva/ChatGptNet/blob/master/samples/ChatGptFunctionCallingConsole/Application.cs#L18) for a complete implementation of this workflow.
