I don't know what's the setMaxTeamSize value in options passed to the test, but if it's big, could it be that doing this sequentially takes a bit too long? I was planning to make a very little team size limit, along these lines:

  let smallTeam =
        opts
          { Opt.optSettings =
              (Opt.optSettings opts)
                { Opt.setTeamInvitationTimeout = 300,
                  Opt.setMaxTeamSize = 5
                }
          }
  withSettingsOverrides smallTeam $ do

I was thinking since tests already run in parallel, we may not gain that much by spawning even more threads, as these are just simple http requests that should be at milisecond response time level in theory (when there isn't anything else ongoing and enough CPU/memory available). Right now the team size is 32 that is inside the hack/helm_vars/... override. Setting maxTeamSize to something smaller is a good idea though, your suggestion makes sense, feel free to adjust this test to this in a separate PR (I see you already merged this one as-is).
