How do I add Razorpay Payment button on contact from 7

I have been using contact form 7 from very long time, I have created page (given link) with “Razorpay Payment button” where the button is added by adding this code "<form><script src="https://checkout.razorpay.com/v1/payment-button.js" data-payment_button_id="pl_JAV93npr1nMQkz" async> </script> </form>" and the same page has CF7 form where I used DOM events and redirected submitted button to “Razorpay Payment landing page”.

All I wanted is instead of redirecting to Razorpay landing page, how can I give Razorpay Payment button as CF7’s submit or send button?

The page I need help with: [log in to see the link]
