I add custom Upload File Plugin. How to send the Uploaded File with Forminator?

Hi.

I built my Order form using Forminator. Because Forminator doesn’t have a “Word Counter for Uploaded file” field, I asked a dev to add that plugin. When someone uploads a file to that plugin, it counts the word in the file, and calculates the total price for Paypal checkout in Forminator.

However, the plugin is outside of Forminator, so it doesn’t send the Uploaded File to my system. Is there a way to fix that?
