Make topbar button work?

[theworkbranch (MET_yamam)]

local Icon = require(ReplicatedStorage.Icon)
local IconController = require(ReplicatedStorage.Icon.IconController)

local icon = Icon.new()
	icon:setLabel("Teams")
	
icon.selected:Connect(function()
	game.StarterGui.MouseButton1Click:Connect(function()
		if game.StarterGui.TeamSwitchGui.MainFrame.Visible == false then
			game.StarterGui.TeamSwitchGui.MainFrame.Visible = true
		else
			game.StarterGui.TeamSwitchGui.MainFrame.Visible = false
		end
	end)
end)

This is my script, I want it when icon is selected, if the GUI visibility is false, it will show the gui, else, it would make it false.
(Using Topbarplus) I can’t fix this. Nothing appears

I think the problem is that you are changing the Game Gui VIsible, not the Player Gui Visible, to fix the problem, you should write this:

local Players = game:GetService("Players")
local player = Players.LocalPlayer
local playerGui = player.PlayerGui
local mainFrame = playerGui:WaitForChild("TeamSwitchGui"):WaitForChild("MainFrame)

And change the main frames’ visible property

There is no signal called StarterGui.MouseButton1Click and TeamSwitchGui is only active inside PlayerGui

local player = game.Players.LocalPlayer
local playerGui = player:WaitForChild("PlayerGui")

icon.selected:Connect(function()
	if playerGui.TeamSwitchGui.MainFrame.Visible == false then
		playerGui.TeamSwitchGui.MainFrame.Visible = true
	else
		playerGui.TeamSwitchGui.MainFrame.Visible = false
	end
end)

Thank you so much, this seemed to have worked.
