First person-third person toggle camera from button

[CactuzMQ (Cactuz)]

I want to create a script that when I click “Onoff” button it changes if its on or off and when I click play button that triggers the camera script go in the first person or not. How can i make it?

Here is my script from play button:

local Sound = script.Parent.Sound
local Plr = game.Players.LocalPlayer
local onoffButton = game.StarterGui.MenuGUI.Frame.Onoff  -- Assuming the button has this path
local onoffState = false  -- Variable to store the state of the "Onoff" button
local ui = script.Parent.Parent
local CurrentCamera = workspace.CurrentCamera
local Part = workspace:WaitForChild("MenuCamera")
local PlayBTN = script.Parent
wait(0.001)
CurrentCamera.CameraType = Enum.CameraType.Scriptable
CurrentCamera.CFrame = Part.CFrame
game.Workspace.MenuCamera.Transparency = 1
game.Workspace.MenuCamera.cutewaballcat.Transparency = 1

local function SetCameraMode()
	if onoffButton.Text == "On" then
		Plr.CameraMode = Enum.CameraMode.LockFirstPerson
	else
		Plr.CameraMode = Enum.CameraMode.Classic
	end
end

script.Parent.MouseButton1Click:Connect(function(click)
	Sound:Play()
	ui:TweenPosition(UDim2.new(0,0,1,0), "InOut", "Sine", 0.5)
	SetCameraMode()
end)

	if Plr.PlayerGui.MenuGUI.Frame.Onoff.Text == "On" then
		Plr.CameraMode = Enum.CameraMode.LockFirstPerson
	elseif Plr.PlayerGui.MenuGUI.Frame.Onoff.Text == "Off" then
		CurrentCamera.CameraType = Enum.CameraType.Custom
		Plr.CameraMode = Enum.CameraMode.Classic
	end
