I am building a products review app with react for a certain company. They require the user's location(country) to show suitable products to review in case users open the app on their own. So, I only found getLocale() in instant games SDK and it's impossible for me to know the user's country through this function, only language is available. I tried react-facebook-login but there doesn't seem to be a permission that gives you location(country) either. I only found one named 'user_location'. However, I couldn't find it on the permissions to request list on facebook dashboard. I also read that I cannot use any third party library that gives me access to user's information outside facebook's sdk.
Any thoughts on how to go through this?
Thank you.
