Question: How do I construct the delta research query ?

This library looks like lacking many more examples of less simplistic queries using graph api for Python .

I am trying to understand how I can delta sync the data using DeltaRequestBuilder that is advocated so much in the documentation, but after installing this package I cannot even find how to import this module from msgraph.
I know I can use another library msgraph-core but it is not ideal either and most examples in Microsoft docs exemplify this library. They do not, however, direct to some comprehensive documentation (or I did not find this).
Beyond that, for my pipeline I need to know how do I rewrite the following HTTP call in the modules of this library:
f"/users/{user_principal_name}/drive/root:/{FolderName}:/children".

Thanks in advance for any response.

Comienza localizando la compatibilidad documentada o exportada del paquete con DeltaRequestBuilder y la ruta de importación de msgraph; después, compárala con los ejemplos de Microsoft referenciados y con msgraph-core. Rastrea los módulos implicados en la solicitud /users/{user_principal_name}/drive/root:/{FolderName}:/children. El trabajo estará terminado cuando la documentación explique las consultas delta, las importaciones y los puntos de entrada equivalentes de la biblioteca con ejemplos funcionales.
