ZipkinExpoterOptions does not contain any definition for ServiceName

Question

 services.AddOpenTelemetryTracing(config => config
            .AddZipkinExporter(o =>
            {
                o.Endpoint = new Uri("http://localhost:9411/api/v1/spans");
                o.ServiceName = "Catalog.Api";
            }));

//Can't able to implement zipkin in my startup class, want to know the exact implementation for zipkin
