How Do You Make A GUI Visible When Clicking An Object That Is In The Workspace?

I'm trying to figure out how to make a GUI turn visible when an object in the workspace is clicked. Is there a way to do so?

Place this in a part with a ClickDetector

script.Parent.ClickDetector.MouseClick:connect(function(player)
	Sg = player.PlayerGui:WaitForChild("ScreenGui") --Gui name
	Sg.Enabled = true
end)

So you are wanting this.

local ClickDetector = script.Parent:FindFirstChild("ClickDetector")
-- Place a 'ClickDetector' in your part!

ClickDetector.MouseClick:Connect(function(click)
if click.Parent:FindFirstChild("Humanoid") then 
local char = click.Parent
local plr = game.Players:GetPlayerFromCharacter(char)
local gui = player.PlayerGui:FindFirstChild("NameOfGUI") -- Enter your GUI name here!

gui.Enabled = true

end
end)

U have to put this script in Part next to the ClickDetector! If script dont work message me! Feel free to accept my answer if I helped you! ;)
