Add script to Thank you page

[NejcZdovc]

Hi all,

I would like to build an app that adds small snippet on Thank you page (Order status page). I see that you can do this kind of things with https://shopify.dev/apps/checkout/post-purchase, but the problem is that this adds steps in between payment and status page. This modifies customer order flow which I want to avoid.

So is there a simple way to create app/extension/script that user can install and adds js snippet in thank you page similar as you can add script to order page via settings?

Thank you
