I wanted to know how can I add a private app and add it to the upgraded checkout page like apps from the Shopify Store? and what credentials should I give the private app in order to see it in the checkout page "Add apps" tab
because meanwhile I created an app and give it permission to the checkout (read, write and branding) but I don't see it in the checkout page customization.
Hey @TomCalmigo - thanks for reaching out. If I'm understanding correctly, you're wanting to integrate an app embed into a shop's checkout page? At the moment, our checkout extensions and apps are available for Plus merchants only - which could be why it's not up as an option on the checkout page. That said - if you are using a Partner Plus Sandbox store and still are unable to add the extension to the page, I'd recommend reaching out to our Partner Support specialists through your Partner dashboard.
They'd be able to get in touch with some other technical teams who can look into why this may be happening. If you do get in touch with them - I'd just refer to this post in the community and they should be able to use it to get more context on the issue.
Hope this helps - let us know if we can clarify anything on our end.
