How to view Google Drive files from connected apps

A free hosting of minecraft offers backups on google drive (https://aternos.org/backups/) but they do not allow me to download them. I would still like to have a local copy. I logged into Google Drive from the same account, but it only shows the files I downloaded, not the Aternos backups. Is there a way to get their hands on them? Or can Google just hide my "files"?
