This is not a code… this is a JSON file… you need a handler code for it… and the link you have… will not do it… also Glide App is already a Web App… so what are you trying to do?
A Glide App IS a Web App. Do you mean converted to a native App?
There is no way to inject code into a Glide App, other than via the JavaScript column or an external code column. And I doubt that either of those will help in this case.
You might struggle to find support for that here. It’s not something that is encouraged or supported by Glide, and if you choose to do it you’re generally on your own.
