alert on subscrption level for any new created resource not getting triggered

I created an alert on subscription level to get notified whenever a resource is created, Action group by email (my email). I created 28 resources using terraform script but no alert was triggered.

general steps I followed:

 1- Scope: Select your subscription. Condition: Search for signal logic: Create Deployment (Microsoft.Resources/deployments). The condition preview should be: Whenever the Activity Log has an event with Category=‘Administrative’, Signal name='Create Deployment (deployments)'.

2 - Create an action group: You can specify the notification type Email

here is a snapshot of the alert config

What is missing? Thanks
