Our recommandations are to create a QR-Code which redirect to your app. Glide does that (very basic one) for you when you click on the big black "share" button.
We suggest you to use tools like QR code Generator to create fanciers ones like the one just right there ➡️
You can do a "static" code (search for it, it's free so a little hidden) and paste your app url (shown in the screenshot ahead) and add a little ribbon (need a registered account).
We also created stickers with an outlet for some of our customers so they can add their table number on it, completely integrated with their design. It's part of the onboarding package you can find on our website ⤵️
