Goodbarber Plugin to pull userdata

The project is developing a Goodbarber Plugin using javascript. Goodbarber is a drag and drop progressive web app builder. Custom plugins can be developed to increase functionality and I have a bunch of developer plugin documentation and GoodBarber's javascript toollkit. User authentication is already set-up in my PWA. However, I need a plugin to be developed to: 1) send all user data from the very limited Goodbarber backend to a google sheet. Update the google sheet with a new row of data whenever a new user signs-up. 2) construct a querystring containing 3 data fields from the logged in user and then pass this data into a Qualtrics survey displayed in an iframe on an app page. Serious freelancers with considerable experience only. Please checkout GoodBarber's javascript toolkit at [login to view URL] Additional plugin documentation from goodbarber is also attached below. Please do not apply without reviewing these items first! Thank You
