SetCore Notifications on only 1 person

Help and Feedback Scripting Support
#1

So I’m creating feature for my game, When someone enters an area, they teleport to another area, but that area isn’t built yet. The game is in its early stages and i still want people to be able to enjoy the new content that I’ve released.

local  enabled = script.Enabled
local TweenService = game:GetService("TweenService")

local Players = game:GetService("Players")


local Teleport = "tp2" 
function Touch(hit)
	if script.Parent.Locked == false and script.Parent.Parent:findFirstChild(Teleport).Locked == false and enabled.Value == true then script.Parent.Locked = true script.Parent.Parent:findFirstChild(Teleport).Locked = true  --Checks Debounce.
		local Pos = script.Parent.Parent:findFirstChild(Teleport) 
		local player = Players:GetPlayerFromCharacter(hit.Parent)

		player.PlayerGui.black.Image.BackgroundTransparency = 0
		
		local tween = TweenService:Create(player.PlayerGui.black.Image, TweenInfo.new(1.3), {BackgroundTransparency = 1})
	

		hit.Parent:moveTo(Pos.Position) wait(5) script.Parent.Locked = false script.Parent.Parent:findFirstChild(Teleport).Locked = false 
		wait(.6)
		tween:Play()
		local CoreGui = player.PlayerGui

		CoreGui:SetCore("SendNotification", {
			Title = "WIP";
			Text = "Unfortunately this feature is not completed. But now you know how to access it!";
			Duration = 5;
		})
	end 
end 
script.Parent.Touched:connect(Touch)

Basically, I’m trying to get ROBLOX’s Notification thing (The box that pops up when someone sends a friend request in game)
to show up for only a single person, But i can’t really figure it out, Maybe I’ve made a simple mistake but some feedback would be appreciated

Run this piece of code:

but on the client rather than the server.
