OnAppendCookie callback doesn't work

services.Configure<CookiePolicyOptions>(
    option =>
    {
        option.MinimumSameSitePolicy = SameSiteMode.None;
        option.HttpOnly = Microsoft.AspNetCore.CookiePolicy.HttpOnlyPolicy.Always;
        option.OnAppendCookie = cookieContext =>
        {
            Console.WriteLine("Cookie appended: " + cookieContext.CookieName);
        };
        option.OnDeleteCookie = context =>
        {
            Console.WriteLine("Cookie deleted: " + context.CookieName);
        };
    });
