Teams AddAsync/PostAsync is totally and utterly broken

Describe the bug
A reasonable person might think that this was the correct usage of the API:
var newteam = await GraphClient.Teams.Request().AddAsync(team, cancellationToken: CancellationToken);
but noooo, that just returns null.

Another reasonable person might see that there is a AddResponseAsync and try:

var channelResponse = await GraphClient.Teams.Request().AddResponseAsync(team, cancellationToken: CancellationToken);
var newteam = await channelResponse.GetResponseObjectAsync();

bot noooooo, that also just returns null. (FYI, there is no overload of GetResponseObjectAsync that takes CancellationToken, which is a bug in itself)

A totally fucking idiot might design the API to actually be called in this way:

         var v = await PostInTaskChannel(MessageFactory.Text(JsonConvert.SerializeObject(team)));
         var channelResponse = await GraphClient.Teams.Request().AddResponseAsync(team, cancellationToken: CancellationToken);
         if (!channelResponse.HttpHeaders.TryGetValues("Location", out var headerValues) ||
             headerValues.First().Split('\'', StringSplitOptions.RemoveEmptyEntries) is not { Length: > 3 } operationRequest)
            throw new("Unknown error, the request did not return the proper response:" + JsonConvert.SerializeObject(channelResponse.HttpHeaders));
         TeamsAsyncOperation? operation = null;
         var firstRequest = true;
         do
         {
            try
            {
               operation = await GraphClient.Teams[operationRequest[1]].Operations[operationRequest[3]].Request().GetAsync(CancellationToken);
               firstRequest = false;
            }
            catch
            {
               if (firstRequest) //sometimes it cannot find the operation, presumable because of hitting another server
                  operation = new() { Status = TeamsAsyncOperationStatus.InProgress };
               else throw;
            }
            if (operation.Status == TeamsAsyncOperationStatus.InProgress)
               await Task.Delay(TimeSpan.FromMilliseconds(100));
         } while (operation.Status is TeamsAsyncOperationStatus.InProgress);

         if (operation.Status is not (TeamsAsyncOperationStatus.Succeeded or TeamsAsyncOperationStatus.NotStarted))
            throw new(JsonConvert.SerializeObject(operation.Error));

         var newTeam = await GraphClient.Teams[operationRequest[1]].Request().GetAsync(CancellationToken);

And why is the last outcome of an successful operation TeamsAsyncOperationStatus.NotStarted?!?!?!?!?

Expected behavior
var newteam = await GraphClient.Teams.Request().AddAsync(team, cancellationToken: CancellationToken);
works... or atleast returns an "TeamsCreationAsyncResult" that can be used to query the further result.
