Where is the Google Tasks folder on Android?

According to this website , it's /data/data/com.google.android.apps.tasks/. On my phone, there's no such folder anywhere. In fact, there's no /data/data anywhere. I do have the Tasks app installed. My Android version is 9, my phone is a Samsung Galaxy J5. I am hoping that I can recover an older version of Tasks' database, because something very important was somehow deleted, that's why I am looking for the folder. Anyone knows where it is?
