[FORMINATOR] Freshsales Integration

I'm looking to add some extra functionality to the forminator plugin. Specifically I would like to add some custom code after the user submits the form to send the data to Freshsales (its like salesforce).

Integration with Zapier which have module for Freshsales does not help in my case.

So I would like to edit the front.submit.js file but I would like to know how to build forminator so that my changes are included in the front.multi.min.js
