I need the user selected locale for the admin panel, in this post: https://community.shopify.com/c/shopify-apps/how-to-display-an-app-in-the-user-s-selected-admin-language/td-p/1936404
They suggest using 2 helper hooks "useShopifyUserLocale" and “useLocale”
However, none of those hooks are available in my application, so how do I get the user-selected locale, kind regards
