Exporting resource files to user:// folder on android

Godot Version

Godot v4.3

Question

Hello I’m new to exporting on android
I’m storing game levels and textures in .tres format files, for now they are in res://levels and res://textures folders respectfully, intention is to store them in user://levels and user://textures, on windows I’d add them using installer but I’m not sure how to do it on android/ios, couldn’t find anything on youtube and by googling. is it even possible to unpack them from .apk/.abb? or should app download these resources on first launch from some server?
