How to get special app folder with the new SDK?

I am pulling my hair out trying to upload to special app folder https://docs.microsoft.com/en-us/onedrive/developer/rest-api/api/drive_get_specialfolder?view=odsp-graph-online

On 5 series, I was simply doing

val specialAppFolder = "approot" val uploadSession = graphServiceClient .me() .drive() .special(specialAppFolder) .itemWithPath(uploadDestination.removePrefix("/")) // removePrefix because OrganiserConverter.fromConfig will return /path/.. .createUploadSession(.....)

On 6+ I cannot figure-out how to get hold of specialAppFolder in order to createUploadSession().

Could someone with a better understanding point me to the right direction please?

該 issue 引用了 Microsoft Graph 關於特殊資料夾的文件，並展示了 v5 Java 呼叫鏈；先將該範例與 v6+ Java SDK 的 API 表面進行比較。確認 approot 資料夾在較新 SDK 中的表示方式，並確認 upload-session 的使用方式，然後記錄由此得出的指引。
