JsonStringEnumConverter

im kinda new to .net9 and expecting to get an enum value as a requestBodyDto,
i did serialization using this code builder.Services.AddControllers()
.AddJsonOptions(options => options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter()));

but on swagger i can still see that its expecting integers instead of string

knowing that we are configuring swagger UI using openApi configuration by reading openapi/v1.json file

so how to fix it?
