Overload of UseHsts Doesn't Seem To Exist #15494

The example under the section "HTTP Strict Transport Security Protocol (HSTS)" where the UseHsts() method is using an overload to provide an anonymous instance of HstsOptions does not seem to be possible using the "ASP.NET Core Web App" ( dotnet new webapp ) template (.NET Core v3.0 in my case). No overload of UseHsts() that takes more than 1 argument cannot be found. I've searched through the source code of the AspNetCore repository and no such overload exists. Where do I find this extension method?
