delta group query call for members

[RaHehl]

I’m referring to #1170.

The last suggested solution there doesn’t seem to match the current version syntactically. I’m currently trying this with the beta client.

How do I make a request like https://graph.microsoft.com/beta/groups/delta?$filter=id eq '1234' using the client?

And how does the skip token work for the subsequent requests that are made at a later time?

PS: When creating an issue, one of the options is "I have a question about usage," and then it suggests opening a discussion instead of an issue. However, it seems that "Discussions" are no longer available in this repository?

[RaHehl]

that seems to be the right call
var result = graphClient.groups().delta().get(requestConfiguration -> requestConfiguration.queryParameters.filter = "id eq '"+groupId+"'");
however, getMembers is null

In the rest request the result that is relevant for me is in the field members@delta

Is it possible that the deserialization for members@delta is missing?

I've got the whole thing working now, but it doesn't seem completely optimal to me. Is it supposed to be like this, or is there a better way to do it?
