Need a JS expert for a simple change on extension

[tomovangel]

Hello guys,

I am using successfully this extension by Stefan Walther

https://github.com/stefanwalther/sense-export

, But because of my huge amounts of data, I need to restrict the calculation of fields before the user has selected certain fields.

So i need to add in this extension, the option from the basic QlikSense Objects:  " Addons" with the Calculation Condition.

I read in this post : Can I use Add-ons in Data Handling in Qlik Sense extension??

that you can do it by adding this lines in the properties panel

addons: {

     uses: "addons",

     items: {

          dataHandling: {

               uses: "dataHandling"

          }

     }

} ,  

But I don't know where to add it.

Can someone make the change inside the file and attach the .zip file here?

Thanks if someone decides to help me

I have tried by my self but I couldn't do it. I have 0 java knowledge...

I am attaching the used version of sense export button.
