Error when searching a specific user in Groups/Members

This is erroring out in V5.
var members = await _graphServiceClient.Groups[groupId].Members[id].GraphUser.GetAsync()

In V4 I could do this NO PROBLEM:
var members = await _graphServiceClient.Groups[groupId].Members[id].Request().GetAsync()

Right now, i have do something funky to get this to work.

  {
      requestConfiguration.QueryParameters.Count = true;
      requestConfiguration.QueryParameters.Filter = $"id eq '{id}'";
      requestConfiguration.Headers.Add("ConsistencyLevel", "eventual");
  });

Am I doing something wrong? Please advise.

Start by reproducing the V5 call to Groups[groupId].Members[id].GraphUser.GetAsync and compare it with the V4 Request().GetAsync call. The issue does not include the resulting error or name a test or source file, so done would require identifying whether the V5 lookup is supported and documenting or correcting the behavior, with coverage if the repository provides a relevant test location.
