Order refund via API

Baically, I want to create system by which my employees can initiate refunds for order without login to the wp-admin panel.
I provide refunds only in Wallet and till now i am directly refunding from the order page by selecting Refund to customer wallet option.
Now for initiating a refund via API I checked this WOO refund api- https://woocommerce.github.io/woocommerce-rest-api-docs/#create-a-refund

But there is no option for select a payment mode for refund. Is there any way i can add refund payment method- terawallet ?

I also knew about your this API- https://github.com/malsubrata/woo-wallet/wiki/WooCommerce-Wallet-REST-API#insert-new-transaction
But for now I wanna avoid that and want to refund directly through Woo API by selectiung payment mode – tera wallet. Let me know if it is possible?
