How can I config the Open API to use the Snake case with the request and response

[VatthanachaiW]

Hi,
Could you please help me configure the Scalar to support the Snake case for the Request and Response?
And I'm not sure if the Newtonsoft. JSON supports the scalar.

In the Service config, I have already config with this.

        builder.Services
            .AddControllers(options =>
            {
              ...
            })
            .AddNewtonsoftJson(options =>
            {
                options.SerializerSettings.TypeNameHandling = Newtonsoft.Json.TypeNameHandling.None;
                options.SerializerSettings.ContractResolver = new DefaultContractResolver { NamingStrategy = new SnakeCaseNamingStrategy() };
            })
            .AddJsonStringEnumConverter()
            .AddJsonOptions(options =>
            {
                
                options.JsonSerializerOptions.PropertyNamingPolicy = new SnakeCaseNamingPolicy();
                options.JsonSerializerOptions.DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingNull;
            });

but in the API Document will displays like this image,

I have already found it. You should be using the 'JsonPropertyName' from the 'System.Text.Json'
