To change the design of an already-created QR code, follow the steps.
Go to your dashboard and select the QR code you want to modify.
Look for the Palette icon, which allows you to change the design of the QR code.
Clicking on the Palette icon will take you to the Design QR code step, where you can adjust various aspects of the QR code's appearance.
From there, you can change the color and shape, add stickers, or incorporate a logo into the QR code to give it a fresh look that suits your preferences or branding needs.
