Brevo to WhatsApp

Hi everyone, I’m trying to understand how to create a scenario that starts from the contact’s name and telephone number from Brevo and then receives a message on WhatsApp. They answered me in Make, but I can’t understand which trigger to use to enter the Brevo scenario.
Do you have any ideas on how to do it? Is there anyone who has a similar situation? Every time I try to look for a trigger with the data to import, name and telephone number I can’t find it…
The person signs up from an autoresponder form that asks for name and telephone number. From here I should insert the link that sends the message on WhatsApp. Is there anyone who can help me?
