I am working on a Shopify theme extension and need to send the Purchase event to Meta through the Meta Pixel. However, theme extensions do not have access to the checkout or thank-you pages, making it difficult to detect when a purchase occurs.

I do have access to the Pixel Extension, but I am unable to retrieve the necessary purchase data within the theme extension itself. How can I accurately detect a completed purchase and send the event to Meta?

Any guidance or workarounds would be appreciated. Thanks!
