delta group query call for members

Describe the bug

var deltaPage = await request.Client.Groups.Delta.GetAsDeltaGetResponseAsync(requestConfiguration =>
 {
     requestConfiguration.QueryParameters.Select = ["id", "displayName", "description", "members", "deletedDateTime"];
     requestConfiguration.QueryParameters.Top = 999;
 });

 await IteratePageAsync(request.Client, deltaPage);

 // Recursively fetch next pages if they exist
 while (deltaPage.OdataNextLink != null)
 {
     deltaPage = await GetDeltaWithUrl(request, deltaPage.OdataNextLink);
 }

 return deltaPage;

<PackageReference Include="Microsoft.Graph" Version="5.56.0" />

In query list groups they always members is null
although I use in graph explorer they always have values in members

Expected behavior

In groups they always responded members when I select in query

How to reproduce

var deltaPage = await request.Client.Groups.Delta.GetAsDeltaGetResponseAsync(requestConfiguration =>
 {
     requestConfiguration.QueryParameters.Select = ["id", "displayName", "description", "members", "deletedDateTime"];
     requestConfiguration.QueryParameters.Top = 999;
 });

 await IteratePageAsync(request.Client, deltaPage);

 // Recursively fetch next pages if they exist
 while (deltaPage.OdataNextLink != null)
 {
     deltaPage = await GetDeltaWithUrl(request, deltaPage.OdataNextLink);
 }

 return deltaPage;

Start by reproducing the Groups delta request shown in the issue with Microsoft.Graph 5.56.0, including the selected members field, and compare its response with Graph Explorer. Check whether the discrepancy is in SDK request generation or the Microsoft Graph response; done means identifying and fixing the SDK behavior or documenting that the service does not return members for this query.
