How do I generate the QR code? [T-Rex 3 Pro]

Hi everyone, sorry if my question has already been answered. I'm completely new to this. I downloaded a watchface to my PC and customized it to my liking using the ZeppOS Watchface Generator, then saved it as a ZIP file. Now I have no idea how to generate a QR code to get the face onto my T-Rex 3 Pro, or if there's another way.
Cheers, Michael from Germany

Ok, i tested it. But the QR don't work. I got the error message: "Parse mini program package failed" or "send package to device failed".
I'm lost.
What's wrong?
What can I do?
Can I test the Face before uploading?
Cheers

Those errors usually mean the file you’re trying to install isn’t a valid package for your watch (wrong format/model, corrupted zip, or built for a different device/OS).
To help you properly, please attach a sample of your watch face file directly in that forum topic (the one I linked earlier). Upload the ZIP/ZPK there (or share a download link), and mention your exact watch model. Then we (or other authors) can check if the package is correct and tell you what needs to be fixed.
