Joplin Android folder

I can not locate the Joplin folder on Android. I see only net.cozic.joplin, but it is empty. Can you help me to find a folder with notes and attachments on Android?

Do you have root on your Android device? You won't be able to see it otherwise.

I don't have root.
Do you mean I can not see the folder, or the folder is net.cozic.joplin, but I can not see files in it?
