WhatsApp send catalog Template

Greeting,

I already sent successfully other template models, but catalog template it fail. There is missing params that's I did not find any exemple online to follow it.

I'm using this code to send catalog template.
var recipientList = new List { phone };
var messageTemplate = new MessageTemplate(templateName, templateLanguage);
var templateContent = new TemplateNotificationContent(Guid.Parse(channelRegistrationId), recipientList, messageTemplate);

// Send template message
var sendTemplateMessageResult = await m_currentNotificationMessagesClient.SendAsync(templateContent);
