Google x Firebase x app

I was able to export one of my tables from the Microsoft Access Database to Google Spreadsheet. That done, I was able to sync the google worksheet with Firebase. Below is the Google spreadsheet and the synchronized firebase database, as well as the application screen.
My question is: Since I am still new to Kodular, I would like to know how I would now pull the data from the firebase into this screen of my application, using a search for this code: 443.

Could someone help me with this?
