Hello and welcome to the community!
At first, on which menu I must set the information?
Application --> aware-processing --> Applications --> Edit ---> Script
Storage --> Advanced --> Scripts
It depends when you want to run the scripts.
In the first case they will take place before and after the job run, in the second case before and after the snapshot creation. By the way in the second case script execution settings can be configured per VM or per container, depending on the objects included in the job.
I guess you need the second one
