Redirect after checkout

[ndsta]

I'm integrating Shopify checkout into an existing application, and trying to do so using Checkout Extensibility. I've built a small app and have almost everything working, but I can't find any way to send users back to my application after checkout is complete. I can console.log the redirect URL on the Thank You page, but I can't find any way of sending users to that URL.

I'd be happy either to:

1. automatically redirect users back to my application after checkout, or

2. change the text and destination of the "Continue Shopping" button to take them back when they click on it.

I can't find a way of doing either of these using Checkout Extensibility. Thanks very much for any information.
