Load from public Documents folder??

Pulling my hair out to do something that is SO simple on Android.

I want to simply have a config text file that I can manually edit on the iOS device and is read once (read only) when my application boots on iOS.

So I've installed a open source text editor on iOS, but it can only access and edits files in the public Documents folder.
Fine.

How can we load from this public Documents location in unity?
Can't use Application.persistentDataPath since it points to the application's private Documents folder

Code (csharp):

1.  
2. /var/mobile/Container/Data/Application/<insert long random name>/Documents

 

Try searching on stackoverflow. It looks like there's some information there but it might be not what you want to hear.
