CORS in Umbraco 10: How to?

Using Umbraco And Getting Started

Umbraco 9

I create this code in program.cs

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureUmbracoDefaults()
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.ConfigureServices(services => services.AddCors(options => options.AddPolicy("MyCors", policy =>
                {
                    policy.AllowAnyOrigin()
                        .AllowAnyHeader()
                        .AllowAnyMethod();
                })));
                webBuilder.UseStaticWebAssets();
                webBuilder.UseStartup<Startup>();
            });
}

and the enabled into startup.cs

public void Configure(IApplicationBuilder app, IWebHostEnvironment env) {

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }


        app.UseCors("MyCors");
        app.UseUmbraco()
            .WithMiddleware(u =>
            {
                u.UseBackOffice();
                u.UseWebsite();
            })
            .WithEndpoints(u =>
            {
                u.UseInstallerEndpoints();
                u.UseBackOfficeEndpoints();
                u.UseWebsiteEndpoints();
            });
    }

But it's not applied the CORS policy and there is not any doc about it. I use U10.2.1. How to? Thanks.

I create this and it works.

Program.cs as by default code. Into the startup.cs:

Into the ConfigureServices:

   services.AddCors(options =>
            {
                //options.AddPolicy("AllowDashboardOrigin",
                //    builder => builder.SetIsOriginAllowed((host) => true).WithOrigins("http://*:*", "https://*:*", "http://localhost:8080", "http://sebapi.redspace.eu", "https://sebapi.azurewebsites.net").AllowAnyMethod().AllowAnyHeader());


                options.AddPolicy("AllowDashboardOrigin",
                             builder => builder.SetIsOriginAllowed((host) => true).AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader());

            });

Then in the Configure add before app.UseUmbraco()...:

app.UseCors("AllowDashboardOrigin");
