Recover default custom data dir path

[2EricBrunet]

Hi,
I have a Galaxy Tab 6S Lite with Saber 0.25.3.
I have recently changed the custom data directory with the "classic" Documents (/storage/emulated/0/Documents/).
But I want to recover some notes located in default dir (/data/user/0/com.adilhanney.saber/app_flutter/Saber)

The interface don't allow the possibility to input text and only display default file explorer which it haven't permission to browse to recover this path (my tablet isn't rooted).
I had tried with "adb shell" with same problem permissions :(

Is it possible to change path directly in a configuration file?
Thanks in advance for your help ^^

There is a bug on custom data directory which should be fixed by #1448
