Hello @Ankur Jain ,
Thank you for reaching out to Microsoft Q&A platform. These kind of alert notifications can be triggered using Azure Monitor->Alerts. I see an option to configure an alert notification every time there is a create or an update action done on the VM image versions
Signal: Create or Update Gallery Image Version (Microsoft.Compute/galleries/images/versions) / Creates a new Gallery Image Version or updates an existing one
Follow the azure monitor alert document here for more details on remaining steps, alerts-overview
