How do I display a Google Sheet calculation result within a WPForms form after submission?

Hi, i am new here and beginning

I Have a form in in wpforms and a google sheet, created a zap that fills some cells in google sheets, then some calculations are made

I want a next step so that i can show the result of the calculation in my wp form.

I tried a plugin but google sheet has to be published again before i can show the results so that doesnt work
