Trying to display/render Post Purchase Checkout Extension preview in embed app page

[vivek-bhalani]

Hey folks,
I am working on adding a Post purchase checkout extension preview inside my custom app’s embedded admin page.
But I haven’t found any clear resources on how to render the preview within the app.
Anyone done this before or have suggestions?

I agree; I have been running into the same thing.

There isn't any proper way to preview checkout extensions during development, which makes testing and merchant preview a bit frustrating.

It would be awesome if Shopify added some kind of dev sandbox or preview mode for this.

Has anyone figured out a better way yet?
