Use resource/language.resx in a class library to another project in ASP.NET CORE 6 - reference

Question

I successfully managed to get Localization/Globalization setup on a project. But had resources in the main project. However, I wanted to move the resources to a class library. I moved them and have referenced the class library, changed the path in the Program.cs and set all the resx properties to "PublicResXFileCodeGenerator" but it's not working, what am I missing?
File structure:
Program.cs code:
using Microsoft.Extensions.Options;
using System.Globalization;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddControllersWithViews();
builder.Services.Configure<RequestLocalizationOptions>(options =>
{
var cultures = new List<CultureInfo> {
new CultureInfo("en"),
new CultureInfo("es")
};
options.DefaultRequestCulture = new Microsoft.AspNetCore.Localization.RequestCulture("en");
options.SupportedCultures = cultures;
options.SupportedUICultures = cultures;
});
builder.Services.AddLocalization(options => options.ResourcesPath = "Resources/Resources");
builder.Services.AddMvc()
.AddViewLocalization(Microsoft.AspNetCore.Mvc.Razor.LanguageViewLocationExpanderFormat.Suffix)
.AddDataAnnotationsLocalization();
var app = builder.Build();
// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
app.UseExceptionHandler("/Home/Error");
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseRequestLocalization(app.Services.GetRequiredService<IOptions<RequestLocalizationOptions>>().Value);
app.UseAuthorization();
app.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
app.Run();
I tried looking online for material but it's saying about linking files etc but mainly with winforms and not .NET6
