Enum type no longer working in .Net core 3.0 FromBody request object

For those who are looking for a snippet when using System.Text.Json

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers().AddJsonOptions(opt =>
    {
        opt.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter());
    });
}

.NET 6 / Top-level statement style

using System.Text.Json.Serialization;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers()
    //convert strings to enums
    .AddJsonOptions(options =>
        options.JsonSerializerOptions.Converters
            .Add(new JsonStringEnumConverter()));
