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.

先找出套件對 DeltaRequestBuilder 和 msgraph 匯入路徑所提供的文件化或匯出支援，然後將其與所參照的 Microsoft 範例和 msgraph-core 進行比較。追蹤涉及 /users/{user_principal_name}/drive/root:/{FolderName}:/children 請求的模組。完成的判定標準是文件說明 delta 查詢、匯入，以及程式庫中對應的入口點，並提供可運作的範例。
