How to access "device config" options file(s) for import/export? (not found in data install location)

[compute-e]

I've been using the version of your XServer XSDL app that's included inside your
useful Android/Fire OS app GIMP Inkscape to run its two GNU/Linux image editors. After that worked well, I found out that the separate version runs the X Window System with the SDL library so can be paired with a command line GNU/Linux emulator to run applications in a graphical user interface with Debian on my tablet device.

I plan to use this individual Android app on the same device, paired with an emulator app. However, I can't find the "device config" options file(s) in the data installation location ("/sdcard") to
export them from the image editing app version and import them (copy over files) into the XSDL app.

Where can I access / find them to re-use for (copy over to) the other version of this app on my device?

Some screenshots linked to this problem:

"Data installation location" option of image editing app version is selected as "SD card storage"	"Specify directory" option of "Data installation location" in image editing app version has default value "/storage/emulated/0/Android/ data/org.gimp.inkscape/files"

Using a file manager app to view the "/storage/emulated/0/Android/data/org.gimp.inkscape/files" folder - no "device config" options file(s) can be found in this data installation location.
