This connector requires Gold subscription

I am completing a course on Elastic Observability Engineer on Demand, Module 6: Actionable Observability Data, and running Lab 6.3 on Alerting, which requires creating an alert on Step 9. While doing this, I am getting a pop-up when I click the email icon, which states that "this connector requires a gold licence"

Hi @topebiggs ,

your environment should have a valid license. You can also start a trial license.

Best,
Andre
