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.

首先定位该包针对 DeltaRequestBuilder 和 msgraph 导入路径的文档化或导出支持，然后将其与所引用的 Microsoft 示例和 msgraph-core 进行比较。跟踪涉及请求 /users/{user_principal_name}/drive/root:/{FolderName}:/children 的模块。完成的标准是文档解释 delta 查询、导入以及库中对应的入口点，并提供可运行的示例。
