@tagolovina : see the comments on the respective files and add the missing params to the param file. Better not use the existing activityUDRUpdatePolicyEffect and activityUDRUpdateAlertState in the new alerts. Let's create new ones

[Brunoga-MS]

@tagolovina : as per agreement during one of our Lead sync call, we need to put [Preview] in front of policies and alert names to set the correct expectations. I would change line 4

from:
"displayName": "Deploy Activity Log Routes Delete Alert",

To:
"displayName": "[Preview] Deploy Activity Log Routes Delete Alert",

@tagolovina : no need to add the alerts here since this file is only kept for backward compatibility. We do not actively use it anymore since the former LandingZone policy was made modular.
