Retrieve Registration Code

[MadameMalady]

I'm working on an option as seen in the 0.2.0 update, to automate registering waydroid images with google play;
My idea currently is to have a script be called and ran by the main app to run the waydroid shell and the line from the waydroid docs to retrieve the code, and write that to a text file, at that point, a square gtk4 window with copy-pastable text should appear displaying the code, with an html link right below it to click and easily register the image.

Currently I get as far as launching the waydroid shell, but idk how to get the command to display the code passed to waydroid's shell and echo'd to a file.

You can examine the script if you'd like to help with this!
