How do you delete instances with RemoteFunctions?

For some reason, there is a button in a SurfaceGUI that cannot be deleted across the entire server. This GUI is supposed to be in PlayerGUI, and I have implemented everything successfully except for this feature that will delete a button on the GUI. Using RemoteFunctions seems to be the best option, for now.

--localScript

local requestMPG = game.ReplicatedStorage:WaitForChild("RequestDeleteMPG")

script.Parent.MouseButton1Down:Connect(function()
	game.Players.LocalPlayer.Character.MPGA.Disabled = false
	
	local deletion = requestMPG:InvokeServer()
end)

--script

local replicatedStorage = game:GetService("ReplicatedStorage")

local deleteMPG = Instance.new("RemoteFunction")
deleteMPG.Parent = replicatedStorage
deleteMPG.Name = "DeleteMPGRequest"

function delete(player)
	print(player .. "has chosen MPG!")
	
	for i, v in pairs(game.Players:GetPlayers()) do
		v.PlayerGui.SurfaceGui.screen.grid.tealGreen:Destroy()
	end
end

deleteMPG.OnServerInvoke = delete
