How to use script in the EPM integration agent?

Summary:

I need to use Groovy script to integration NetSuite with PBCS. How to trigger it in PBCS?

Content (please ensure you mask any confidential information):

The EPM Agent is setup and running. The BefExtract.groovy script is put into the script folder C:\EPMAgentData\scripts.

In the agentparams.ini file, the GROOVY_HOME is configured.

I would like to know how to configure the settings in PBCS to trigger the script.

How to setup the source application? What category should I use? Or any other settings I need?

Appreciate the help.
