✅ .net 7 rest api CORS issue with Authentication

Hey so I'm trying to set up something I've never done before so I can get the PC name of people connecting to my API (This is a business Intranet website that calls the api)

blah blah blah

builder.Services.AddSingleton<DapperContext>();
builder.Services.AddScoped<IRepo, Repo>();

            policy.WithOrigins("http://localhost:4200/",
                                "https://localhost:4200/").AllowAnyMethod().AllowAnyHeader().AllowCredentials();
        });
});
builder.Services.AddAuthentication(NegotiateDefaults.AuthenticationScheme)
   .AddNegotiate(); // which used by microsoft.aspnetcore.authentication.negotiate nuget package
builder.Services.AddAuthorization(options =>
{
    // By default, all incoming requests will be authorized according to the default policy.
    options.FallbackPolicy = options.DefaultPolicy;
});



builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();
//after app intialization:
app.UseCors();
app.UseAuthentication();
app.UseAuthorization();





// Configure the HTTP request pipeline.
