Venia PWA - Handle POST requests using react router dom

[TheRealHunzik]

Is there a way to handle POST requests using the react-router-dom (npm) library?
Why? The payment gateway will redirect the user, who successfully paid, back to the platform. which is using POST request to transfer data with the redirection page. I want to get the data in react js so I can use it further in my placeOrder Mutation
One Method I saw is to add an Express route in the Upward.js file but I want to add this route using my custom package, can anyone guide me More about this Method #2552
Thank You (edited)
