 To register your custom function you need to specify a function `name`, function `description` that helps the model to understand when to call the function, and the function call `signature` (as JSON schema) to let the model know what arguments the function expects.
 Then you can implement a function that takes the function call arguments from the model interacts with the external, 3rd party, services and returns the result back to the model.
