How can i define where a player clicks?

Im doing a place tool which places blocks, but i can't define where somebody clicked, so i dont know where can i place the block. Here is the script.

	local Tool = script.Parent
 
Tool.Equipped:connect(function(Mouse)
	Mouse.Button1Down:connect(function(location)
			local part = Instance.new('Part')
	part.Parent = workspace
	part.Anchored = true
	part.CFrame = location
	local sbox = Instance.new("SelectionBox")
	sbox.Name = "sbox"
	sbox.Adornee = part
	sbox.Parent = part
	end)
		Mouse.Button1Up:connect(function()
		game.Workspace.Part.sbox:remove()
		wait(30)
		game.Workspace.Part:remove()
	end)
end)
