This asset works perfectly. It was quite simple to use it in my application.
From installing to make it working in my app it took only five minutes.
The asset itself has all needed documentation. You can customize some characteristics like the background/foreground of the QR code, which is nice.
I believe that all elements have descriptions so great care has been put in it to make this asset easy  to understand.
Thank you for making and sharing this asset!

Tested with OutSystemsUI Version 2.12.0
