The code samples in the readme are not idiomatic C#

An aesthetic, cosmetic issue, for sure, but nonetheless, here it goes:

This:

WhatsAppBusinessCloudApiConfig whatsAppConfig = new WhatsAppBusinessCloudApiConfig();
whatsAppConfig.WhatsAppBusinessPhoneNumberId = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessPhoneNumberId"];
whatsAppConfig.WhatsAppBusinessAccountId = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessAccountId"];
whatsAppConfig.WhatsAppBusinessId = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessId"];
whatsAppConfig.AccessToken = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["AccessToken"];
builder.Services.AddWhatsAppBusinessCloudApiService(whatsAppConfig);

Is not idiomatic C#. In this particular case, since you're using the dotnet configuration API you might simply map the config section to your configuration object:

// this will contain all values from the config/environment, without the need for manual mapping.
var whatsappConfig = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration").Get<WhatsAppBusinessCloudApiConfig>(); 

builder.Services.AddWhatsAppBusinessCloudApiService(whatsappConfig);

Also here:

TextMessageRequest textMessageRequest = new TextMessageRequest();
textMessageRequest.To = "Recipient Phone Number";
textMessageRequest.Text = new WhatsAppText();
textMessageRequest.Text.Body = "Message Body";
textMessageRequest.Text.PreviewUrl = false;

it should be using object initializer syntax:

var textMessageRequest = new TextMessageRequest
{
    To = "Recipient Phone Number",
    Text = new WhatsAppText
    {
        Body = "Message Body",
        PreviewUrl = false
    }
};

Same with many other code samples.

I can create a PR fixing this if you want.
