Custom labels added using pyroscope dotnet nuget are not available

Grafana Pyroscope

I am trying to add custom labels for one of my webapi

snippet:

    public ActionResult<IEnumerable<string>> GetTestList()
    {
        IEnumerable<string> result = new List<string>();
        Pyroscope.LabelSet labels = Pyroscope.LabelSet.Empty.BuildUpon()
.Add("api_endpoint", "getunittestslist")
.Build();
        Pyroscope.LabelsWrapper.Do(labels, () =>
        {
            result = TestService.GetTestsIds();
        });
        
        return StatusCode(200, result.ToList());
    }

I have added 5 seconds of delay internally to test latency
