Can't access Shared Google Drive Folder on One App

What I’m trying to do:
Use Google API to connect to a shared folder that has a Sheets file I need

It works on one app - I see the files and folder I set this one up a while ago and use it often

The new app I want it on has the same config, same google account, same files in drive showing EXCEPT for this shared folder - can’t find out why it would show before when I made the other app but not anymore

TLDR: One app is connected to a shared google drive folder/file but another app can’t see the shared folder/files but sees everything else the same.
