How do I add a live currency exchange rate to my Shopify store?

If you are running an online store on Shopify, you may want to add a live currency exchange rate to your store in order to provide customers with accurate pricing information in their local currency. This can help to increase customer trust and make it easier for customers to make purchases from your store, as they will know exactly how much they are paying in their own currency. Additionally, having a live currency exchange rate can help to reduce the risk of currency fluctuations, as customers will be able to see the exact exchange rate at the time of purchase.
