Indeed, these folders are seen by a file manager in internal storage/Android/data/
The location /data/data/foundation.e.notes/databases/OWNCLOUD_NOTES is not found by most file managers.
That is why in my case looking for the databases with TWRP seemed the easiest thing (for me).
In this post Notes on phone that wouldn’t sync lost after OS update. Any hope of recovery? - #11 by aibd I confidently said that I thought a Samsung (like yours) would have TWRP installed – however I overlooked that many devices now overwrite TWRP with /e/Recovery. (/e/Recovery does not include a file manager, so is not useful for this task.)
You might use that guidance to see if you do have TWRP recovery.
In yet another thread Notes doesn't work after yesterday update - #3 by namib it has been revealed that notes appear to continue to exist on Murena cloud. It is worth checking this in your case, as this might offer much easier recovery of the Notes.
