How to fetch InApp Purchase Product Prices in Local currency in iOS?

Question

I am implementing InApp Purchase Products in AppStoreConnect where we get to choose the price in Dollars($). Let's say I have created a Product with the Price of $0.99 which is equivalent to £0.89. Now I want to display the equivalent price of United Kingdom in my App. But unfortunately All I am able to achieve is to get £0.99 from different solutions that provides locale price based on the settings. But this is wrong as I want to ideally display the actual price in GBP which is only 0.89 and not 0.99.

Any help in resolving this would be very helpful.

P.S:- I have tried solutions from How to get locale currency price for in-app purchases in iOS? but none seem to work properly.
