How do i make GUI visible and invisible with commands

Hi, does anyone know how to make a command (Ranks only) to make a GUI visible/invisible? Like when you say “:GUI on” it will make the GUI visible, when you say “:GUI off” it will make the GUI invisible, that affects everyone’s screens. And only some roles can use it (Just like commands for ranks)

Utilize usage of Player.Added and get the players rank from a group using one of the functions in the Players service, and then use remote events to affect the GUI visibility.

When a player joins your game you can attach a player.Chatted connection to them and when a player chats the command and has the rank for that command(with a simple if statement), the server can fire a remote event to all the clients and when the clients recieve it all their guiobjects can just set their visible property to false

Use this Topic to make the Command: How To: Make Chat Commands

And use this Topic to Detect Player Group Ranks: Player:GetRankInGroup

And in the first Topic change the code a bit and add GUI.Visible Properties.

Here is a quick example. This requires a RemoteEvent in ReplicatedStorage named UI_Visible

-- server
game.Players.PlayerAdded:Connect(function(plr)
	if plr:GetRankInGroup(groupId) >= groupRole then -- replace the following with your group id and group role
	plr.Chatted:Connect(function(msg)
		if string.lower(msg) == ":gui off" then
			game.ReplicatedStorage.UI_VISIBLE:FireAllClients(false)
		end
		if string.lower(msg) == ":gui on" then
				game.ReplicatedStorage.UI_VISIBLE:FireAllClients(true)
			end	
		end)
	end
end)

-- client
local UI = script.Parent.Frame -- make this the path to whatever UI you want to disable


local function changeVisibility(bool)
	UI.Visible = bool
end

game.ReplicatedStorage.UI_VISIBLE.OnClientEvent:Connect(changeVisibility)

local players = game:GetService("Players")

local groupId = 0 --Change to ID of group.
local groupRank = 0 --Change to required rank.

local function isInGroup(player)
	local success, result = pcall(player.IsInGroup, player, groupId)
	if success then
		if result then
			return true
		else
			return false
		end
	else
		warn(result)
		return nil
	end
end

local function hasGroupRank(player)
	local success, result = pcall(player.GetRankInGroup, player, groupId)
	if success then
		if result then
			if result > groupRank then
				return true
			else
				return false
			end
		end
	else
		warn(result)
		return nil
	end
end

local function onPlayerAdded(player)
	local function onPlayerChatted(message)
		if message:lower():match("^/guion$") then
			if isInGroup(player) then
				if hasGroupRank(player) then
					for _, player in ipairs(players:GetPlayers()) do
						player.PlayerGui.ScreenGui.Enabled = true
					end
				end
			end
		elseif message:lower():match("^/guioff$") then
			if isInGroup(player) then
				if hasGroupRank(player) then
					for _, player in ipairs(players:GetPlayers()) do
						player.PlayerGui.ScreenGui.Enabled = false
					end
				end
			end
		end
	end
	
	player.Chatted:Connect(onPlayerChatted)
end

players.PlayerAdded:Connect(onPlayerAdded)

The commands are /guion and /guioff to enable/disable every player’s gui respectively.
