product price doesn’t shown with the selected currency on all page of my website (only on cart and checkout page)

my website is multi-language , i use wp rocket as a cache plugin , i want to offer the choice to the user to select his currency either USD or by default th SAR currency , so i choose ti install premium curcy plugin , it only works on cart and checkout page , while i have products on home , shop , single product page , so my goal is to display the price with the selected currency over all the pages on the website .
