Healthcheck page is Blank

[LR4Discovery]

I am trying to get HealthCheckUI work with APIVersioning. After getting bunch of errors i modified the endpoint mappings to include V1 prefix. When i try to bring up https://localhost:44380/v1/healthcheck i get a blank page. Any documentation, suggestions on how to use HelathCheck UI with multi-versioned API

endpoints.MapHealthChecks("/V1/healthcheck", new CustomHealthCheckOptions());
endpoints.MapHealthChecksUI(setup =>
{
    setup.AddCustomStylesheet("Controllers/V1/HealthCheck/dotnet.css");
    setup.UIPath = "/V1/healthcheck";
    
});

Thank you
