Wie kann ich meine Bitcoin-Geschenkkarte wiederherstellen?

I'm wondering, how can I restore my Bitcoin gift card? I've recently misplaced it and I'm quite concerned about losing access to the funds associated with it. Could you please provide a step-by-step guide on how to proceed? I've tried searching online but most of the information is quite overwhelming and technical. I'm hoping for a simpler explanation tailored specifically for a Bitcoin gift card restoration process. Thank you for your help in this matter.
