client.Users.GetByIds.PostAsGetByIdsPostResponseAsync Does not allow for $select parameter

[mligtenberg]

Describe the bug

I would like to select a group of users with their known identities by doing the following request:

POST /v1.0/users/getByIds?$select=id,displayName,identities HTTP/1.1
Host: graph.microsoft.com
Content-Type: application/json
Content-Length: 48

{"ids":["aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa"]}

This should be translate to something like the following in C#

var user = await client.Users
    .GetByIds.PostAsGetByIdsPostResponseAsync(new GetByIdsPostRequestBody()
    {
        Ids = ["aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa"],
    }, cfg => 
    {
        cfg.QueryParameters.Select = ["id", "displayName", "identities"];
    });

However the cfg.QueryParameters.Select property is not available for client.Users.GetByIds.PostAsGetByIdsPostResponseAsync() request

Expected behavior

The Select query parameter should be available in the PostAsGetByIdsPostResponseAsync configuration body, as it is available in the actual api

How to reproduce

Use the following code snippet:

var user = await client.Users
    .GetByIds.PostAsGetByIdsPostResponseAsync(new GetByIdsPostRequestBody()
    {
        Ids = ["aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa"],
    }, cfg => 
    {
        cfg.QueryParameters.Select = ["id", "displayName", "identities"];
    });

Known Workarounds

non,

something like the following should work, but the query parameters are ignored:

var postRequest = client.Users.GetByIds.ToPostRequestInformation(new()
{
    Ids = ["aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa"]
});

postRequest.QueryParameters.Add("%24select", "id,displayName,identities");
var users = await client.RequestAdapter.SendAsync<GetByIdsPostResponse>(postRequest, GetByIdsPostResponse.CreateFromDiscriminatorValue);

Debug output

No response

I found a work around, the UrlTemplate is also incorrect and should be expanded.
The below code is working (though really ugly)

var requestInfo = client.Users.GetByIds.ToPostRequestInformation(new()
{
    Ids = ["aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa"],
});

requestInfo.UrlTemplate += "{?%24expand,%24select}";
requestInfo.QueryParameters.Add("%24select", new [] {"id","displayName","identities","mail"});

var response = await client.RequestAdapter.SendAsync<GetByIdsPostResponse>(requestInfo, GetByIdsPostResponse.CreateFromDiscriminatorValue);

var users = response?.Value?.OfType<User>() ?? [];
