Built In Google Sheets Component for App Inventor

Wandering onto a closed construction site is risky.
While we wait for announcement by MIT as to the disposition of the Tommy Heng blocks,

That approach has the advantage of not requiring special servers or Companion versions, at the expense of learning to do some scripting.

Regarding your data structure and sheet design, I have a sample for a Pizza Store further up in this thread, using the app name APizzaSheet (pun intended.)

Dealing with multiple Companion versions is easier if you use alternative emulators.
