How do I use a SurfaceGui to teleport a player to a specified location?

The SurfaceGui is located in a Part of a Group, and inside the SurfaceGui is a TextButton that has a LocalScript. The LocalScript is supposed to teleport the player clicking the TextButton to a specified location, but I don't know how to make the LocalScript do that in my code .

local p = game.Players.LocalPlayer
local body = p.Character.HumanoidRootPart --HumanoidRootPart is used to make the game compatible with R15

function onClicked(GUI)
      body.CFrame = CFrame.new(Vector3.new( -281, 60.2, 238 ))
end

script.Parent.MouseButton1Click:connect(onClicked)

move the SurfaceGui to StarterGui and change the Localscript to this V

local p = game.Players.LocalPlayer
local player = game.Players:FindFirstChild(p.Name)
script.Parent.Parent.Parent.Adornee = game.Workspace(CHANGE THIS)
local body = p.Character.HumanoidRootPart --HumanoidRootPart is used to make the game compatible with R15

script.Parent.MouseButton1Click:connect(function()	
	
      body.CFrame = CFrame.new(Vector3.new( -281, 60.2, 238 ))
end)

line 3 will make it visible on the part when they join and it will get the name of the player since the surfacegui is in their playerGui, it's easily to find their name

dont forget to change the part on Line 3
