File access control APP and warning / alerting messages

I like this App to control file access.
We need a possible extension.
The use case is a user that is accessing a file, and the access to the file is blocked.
How can we add a message of warning /alert to the admin(s) or have a flexible way to manage this event?
A second use case is to have a message as this file is classified “tags” (like “top secret”) ask your manager the grant to access this file."
Do you have a possible solution for this feature?
Thank you
