Cancelling a partial refund

[sengming]

Hi there,

I created a partial refund using the Admin REST API https://shopify.dev/docs/api/admin-rest/2023-07/resources/refund#post-orders-order-id-refunds

The partial refund was successful. However it looks like I do not want that refund at all.

How do I cancel the refund? I couldn't find any information here

Thanks!
