How do I add a QR code?

To add a QR code for an inventory item, click on the corresponding inventory in the overview. In the detail view, navigate to the "QR Code" section and click the "Scan New QR Code" or "Enter New QR Code" button. Either the scanner will open or a dialog with a text field will appear. The QR code will be validated upon addition, and if it is not already assigned, it will be successfully added.
