Custom Pull from Google Sheets and Calendar for React Native API

To start: I am a beginner in React Native design…

I am trying to find a way to have a Google Sheets and a Google Calendar that is linked to two different iOS and Android React Native apps. I want to be able to input in the calendar or sheet and it show up in the app. All of the tutorial videos I have found go about it the other way around where it takes inputs from app and adds them to Google account.

Does anyone have documentation or know of a few videos that do this?
