To send a message, you can use specific builders based on the type of message. Here are examples for text, image, and template messages.

Example: Sending a Text Message

const client = new Client({
  token: 'YOUR_WHATSAPP_TOKEN',
  baseURL: 'https://graph.facebook.com/v22.0/YOUR_PHONE_ID',
});

const sendMessageUseCase = new SendMessage(client);

const message = new TextMessageBuilder()
  .setRecipient('5511999999999')
  .setText('Hello World')
  .build();

sendMessageUseCase
  .execute(message)
  .then(() => console.log('Success send message!'))
  .catch((error) => console.error('Error', error));
