cannot be used QR Code again

Problem/Motivation

Hay,

I cannot use the QR Code again on every refresh page he changes.

I have a site where every invite has a code to check if has access or not but the QR code is changed how to check?

I can't share it with anyone because it changes.

Steps to reproduce

After creating the field and creating a new node just refresh the page he is change ):.

Proposed resolution

save the QR code image and the text like if I use the date he saved: Example 2023-09-23.
OR
add settings at the field to if you need to change every time or save the image and text.
