I have no idea the answer to your question, but personally, I find digital QR menus to be very poor UX. I know they've been around for a long time, but in my area I've only started seeing them more commonly the past few months; it seems the pandemic has driven a lot of restaurants to get rid of paper menus (hopefully temporarily).
We have a young kid and most of the time one of us (my spouse or myself) have to be paying attention to her, especially while outside. Looking at a restaurant menu on a mobile phone makes it pretty much impossible to look at and share and discuss items on the menu, while the other person can only pay 20% of attention (because the other 80% attention is on the kid). The end result is usually one person can't really order what they want. Paper menus are larger, have pictures, easier to flip around pages or sides, easier to point to things between two people (when one is not paying full attention) and generally more visible (when one is not paying full attention).
It's bad enough that we either avoid places with digital menu or have to make plans in advance to be sure we look through the menu at home the day before going.
