Changing Camera Type to DevCameraOcclusionMode - Invisicam?

I am trying to change the camera to invisicam. So its a 2D camera script, and I thought when a player walks behind a wall you want to be able to seem them. So why not use the Invisicam that comes with Studio. I havent been able to figure out the function to change the camera mode on spawn.

Heres what ive got so far, I am still figuring out all this scripting stuff its new to me so ive got a juicy bit of questions.

local Camera = game.Workspace.CurrentCamera
local Player = game.Players.LocalPlayer

repeat
  wait()
until Player.Character

local Character = Player.Character
local Player_Torso = Character.UpperTorso

-------------------------------------------------------------------

Camera.CameraType = Enum.CameraType.Scriptable
Camera.CameraSubject = Player_Torso

game:GetService("RunService").RenderStepped:connect(function()
	if Player.Character and Player.Character:FindFirstChild('UpperTorso') then
	Camera.CFrame = CFrame.new(Player_Torso.CFrame.X, Player_Torso.CFrame.Y + 1.5, Player_Torso.CFrame.Z + 13)
	end
end)

-------------------------------------------------------------------

game:GetService("RunService").RenderStepped:connect(function()
	if Player.Character and Player.Character:FindFirstChild('UpperTorso') then
		Player:DevCameraOcclusionMode
	end

This ^ last block of code is the one that will call the camera change, but I cant seem to find the right one. Ive tried many different things but its been a while since ive scripted last.

Thank you for your time.
