is there a way to detect newly created application?

I'm planning to run a nightly process that will see if any new application has been created for the past 24 hours, and then send notification with some instructions to the person who created the new application. 

is there a way to detect these new application containers? any plug-in I can utilize? 

We self manage Appian on Kubernetes, so we have access to logs and Appian metadata.
