How to sens sms through Grafana?

I want to send SMS in Grafana. How can I do that? If I'm going to use Twilio, how can I integrate it? I'm running Grafana with Docker. I've created an alert in Grafana, and in the Notification section, I can define an email in the Contact Point and send emails. I thought about using a webhook in the Contact Point, but I'm not sure how to define the script. https://www.pulumi.com/ai/answers/pck5gRTpY63C4TRkXNhvfK/architecture-grafana-alerts-to-twilio-sms Can you help me understand how to define the script in the Contact Point for webhook in Grafana?"
