Google Sheets data to MIT App Inventor

Hello,
I am posting this on behalf of one of my students.

I am making an app to get homework for kids, using google sheets that I do not own. At the moment I am manually updating the app weekly, I would like to make it so that the app will update itself weekly. Ideally, I would like the app to update every time a teacher puts in a homework assignment, but I am an amateur coder and do not have much experience. I have tried many different tactics such as using google forms, but none seem to work.

If anybody could help it would be greatly appreciated.
Thank you,
Marissa

Here is my code:
