More calls required for a Thumbnail Retrieval in Microsoft Graph SDK Version 5

Title: Resolving Thumbnail Retrieval Issues in Microsoft Graph SDK Version 4

Hello,

In version 4 of the Microsoft Graph SDK, I was previously able to retrieve file thumbnails using the following request:

await client.Groups[id.ToString()].Drive.Root.ItemWithPath($"/{_uploadConfiguration.FolderRelativeUrl}").Children.Request().Expand("thumbnails").GetAsync();

However, constructing this path alongside a group context no longer seems to function as expected with the version 5 of the Microsoft Graph SDK. To work around this, I found an alternative approach that requires making two separate calls to the Graph API:

var rootDrive = await this._graphServiceClient.Groups[id.ToString()].Drive.GetAsync();

var items = await this._graphServiceClient.Drives[rootDrive?.Id]
    .Root
    .ItemWithPath($"/{_uploadConfiguration.FolderRelativeUrl}")
    .Children
    .GetAsync(requestConfiguration =>
    {
        requestConfiguration.QueryParameters.Expand = new[] { "thumbnails" };
    });

This solution, however, is less efficient than the previous single-call method. Am I missing any configuration in the new SDK to achieve my initial objective, or is this a possible bug in the current SDK?

I am experiencing the same issue with this call.

this._graphServiceClient.Groups[groupId].Drive.Root.Request().GetAsync();

Thank you for your help,
Patrick
