I am an app developer and trying to send the pixel migration instructions to clients using new Checkout extensibility.

Is there a way to check from the store’s online URL whether the store is using the new Checkout extensibility or not? (Ex: Inspecting the browser’s network call and checking for any specific JS file being loaded or checking for any window object)
