How to create a new folder in root of some Drive?
Documentation suggests to use post request to "me/drive/root/children". But Root request builder does not have Children collection, so the code can not be compiled:

await client.Drives[someDriveId].Root.Children.PostAsync(newFolderItem);

Is it safe to use ItemWithPath("/") for this case?

await client.Drives[someDriveId].Root.ItemWithPath("/").Children.PostAsync(newFolderItem)
