create AddLanguageContainerSupportService.cs inside your project then replase every thing inside the class with next code

using System.Globalization;
using System.Reflection;
using Microsoft.Extensions.DependencyInjection;

namespace AKSoftware.Localization.MultiLanguages;

public static class AddLanguageContainerSupportExtensions
{
    public static IServiceCollection AddAddLanguageContainerSupport(
        this IServiceCollection services,
        Assembly assembly,
        string folderName = "Resources")
    {
       return services.AddSingleton<IAddLanguageContainerSupportService, AddLanguageContainerSupportService>(s => new AddLanguageContainerSupportService(assembly, folderName));
    }
}

public interface IAddLanguageContainerSupportService
{
    List<CultureInfo> GetSupportedCultures();
}

public class AddLanguageContainerSupportService : IAddLanguageContainerSupportService
{
    private readonly Assembly _assembly;
    private readonly string _folderName;

    public AddLanguageContainerSupportService(Assembly assembly, string folderName)
    {
        _assembly = assembly;
        _folderName = folderName;
    }

    public List<CultureInfo> GetSupportedCultures()
    {
        var languagesYamlFileNames = GetLanguagesYamlFileNames();
        if (languagesYamlFileNames == null || !languagesYamlFileNames.Any())
        {
            return new List<CultureInfo>();
        }

        var cultures = languagesYamlFileNames
            .Select(s => s.Split('.')[^2])
            .Select(s => new CultureInfo(s))
            .ToList();
        return cultures;
    }

    private List<string>? GetLanguagesYamlFileNames()
    {
        try
        {
            return _assembly
                .GetManifestResourceNames()
                .Where(s =>
                    s.Contains(_folderName) &&
                    (s.Contains(".yml") ||
                     s.Contains(".yaml")) &&
                    s.Contains("-"))
                .ToList();
        }
        catch (Exception ex)
        {
            // Handle the error as needed
            Console.WriteLine($"Error: {ex.Message}");
        }
        return new List<string>();
    }
}

in Program.cs file after

builder.Services.AddLanguageContainerForBlazorServer<EmbeddedResourceKeysProvider>(Assembly.GetExecutingAssembly(), "Resources");

add

builder.Services.AddAddLanguageContainerSupport(Assembly.GetExecutingAssembly());

then in your Combonent add

...
@inject IAddLanguageContainerSupportService LanguageContainerSupport

@foreach (var culture in LanguageContainerSupport.GetSupportedCultures())
          {
              <img src="@($"https://flagsapi.com/{culture.Name.Split("-")[1].ToUpper()}/shiny/64.png")"
                   @onclick='() => SetLanguage(culture.Name)' style="width:75px;cursor:pointer;margin:10px"/>
          }

...

by call LanguageContainerSupport.GetSupportedCultures() you will get List<CultureInfo> of all available Languages
