The 'Friend Requests' tab is a new feature that allows you to easily see who has sent you a friend request. You can find this tab in the same place where your friends are displayed at the top right, next to the notification icon. Simply click the friends icon to access it.

You don’t have to decide immediately what to do with a friend request you can store them and respond whenever you’re ready. 

You will still receive a notification each time you get a friend request, but if you happen to miss it, you’ll always know where to find it. Every friend request will be stored there indefinitely, and there is no limit to how many requests you can keep.
