How can I create a custom “Order Received” page after checkout in my ecommerce website?

Question

I’ve built an ecommerce website and I’ve already created the checkout page successfully. Now I want to create a custom “Order Received” page that appears after a customer completes the checkout process.

My goal is to make it show the order summary, thank-you message, and a clean design matching the site’s theme.

Here’s my website for reference: https://commedesgarconsstores dot com/

Can anyone guide me on how to link the checkout page with the “Order Received” page properly, and what’s the best way to handle order confirmation data (like order ID, total, etc.) on that final page?
