How do I clone a gui and put it in everybody's playerGui?

I'm still making that announcement system, and I still need a lot of help. While testing, my announcement system works, but only on the client. I still have no idea how to do this and remote events still don't work for me. Any help? Here's my script again. (Localscript)

script.Parent.MouseButton1Up:Connect(function()
	local set = script.Parent.Parent.Set
	local text = set.Text
	local label = script.Parent.Parent.Parent.Parent.Announcement.TextLabel.TextLabel
	local frame = script.Parent.Parent
	local ammount = script.Parent.Parent.Time.Text
	
	frame:TweenPosition(
		UDim2.new(0.5,0,0.6,0), --ending position
		"Out", --how it eases
		"Quad", --styleeee
		0.7, --the time it takes
		false --wont override anything else
	)

	label.Text = text
	label.Parent:TweenPosition(
		UDim2.new(0.5,0,0.1,0),
		"Out",
		"Quad",
		1,
		false
	)
	wait(ammount)
	frame:TweenPosition(
		UDim2.new(0.5,0,0.5,0),
		"Out",
		"Quad",
		0.7,
		false
	)
	label.Parent:TweenPosition(
		UDim2.new(0.5,0,-1.1,0),
		"In",
		"Quad",
		1,
		false
	)
end)

Here is video of me using it: https://www.youtube.com/watch?v=2Kwji4Xk7zY&feature=youtu.be
