Build the solution as said inside of the README.md
Modify your discord-tickets solution TICKETS worker to not decrypt, instead, to serve the encrypted as plaintext.
Once you do that, restart your bot and panel, and export. Take the tickets.jsonl file and put it inside of your working directory.
Run the executable, and then let the program do its thing.
Enjoy! Once done, rename the file as tickets.jsonl, and re-create the WinRar/7-Zip archive and import the files.
