How can I edit the code to change the return request approved email on prestige theme?

I am based in the UK and I am using Shopify customer accounts to process returns. The issue I have encountered is that the return request emails are based on the US and providing a shipping label. Can the return request approved email be changed to a generic piece of text that outlines how the customer can return their order and includes all the info they need?
