Cannot send order_details to customers in India

We tried sending order_details (interactive) to the customers. And we are getting the error
{"error":{"message":"(#131009) Parameter value is not valid","type":"OAuthException","code":131009,"error_data":{"messaging_product":"whatsapp","details":"Interactive Message type, 'order_details' not supported. Supported types ['button', 'list']"}
We tried using the below link to opt in for payments, but the form doesn't submit data and shows error https://www.facebook.com/help/contact/322487863689187
We came across a support article to add payment gateway integration for India (Razorpay / PayU). But when we try to add payments, it only shows Singapore as the country with Stripe as the option.
How do we enable payments from India using In-app UPI. We currently have fallen back to payment links being sent from Razorpay (without in-app payment flow)
