Roblox really wants to push social, they’ve spoken about that.
Right now you are able to prompt a player to send a friend request, but no way to notify the other player that they were sent one.
The default notification sent is very easy to miss, and if you have a custom leaderboard then if you miss the notification you miss the friend request completely.
Please add an event that is fired when a player receives a friend request
We have events for whenever a player is friended or unfriended via StarterGui:GetCore("PlayerFriendedEvent")/StarterGui:GetCore("PlayerUnfriendedEvent")
It would make sense to add an event for when a friend request is sent, especially from StarterGui:SetCore("PromptSendFriendRequest")
Perhaps StarterGui:GetCore("PlayerSentFriendRequestEvent") and StarterGui:GetCore("PlayerReceivedFriendRequestEvent") would work.
