How to add ApplicationService in .Net 6

Question

I created a Service class in .Net 6. How to call it in .net 6?

.Net 6

using API.Data;
using API.Interfaces;
using API.Services;
using Microsoft.EntityFrameworkCore;

namespace API.Extensions
{
    public static class ApplicationServiceExtensions
    {
        public static IServiceCollection AddApplicationServices(this IServiceCollection services, IConfiguration config, WebApplicationBuilder builder)
        {
            builder.Services.AddDbContext<DataContext>(options =>
            {
                options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection"));
            });
            builder.Services.AddScoped<ITokenService, TokenService>();
        }
    }
}

I was calling it as given below.

.net core 3

public void ConfigureServices(IServiceCollection services)
{
services.AddApplicationServices(_config);
}

When I try to call like this. It shows an error Can anyone suggest the right way to call it?

Program.cs .net 6

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddApplicationServices(_config);
