How can I make the mouse move freely when having the camera over my shoulder

Help and Feedback Scripting Support
#1

Well, well, I already made a post about this, but I wanted no mouse click to move the camera, and I was given a link to the developer that says on the subject. The difference with the other post and this one, is that in this one I want the mouse to be able to move freely after pressing a key. From what I have seen, when pressing the pause button, you can move the mouse freely, I want to achieve the same but pressing another button (open the map with the “M” key)

Here is the script in case you do not want to enter the developer 
local Players = game:GetService("Players")
local ContextActionService = game:GetService("ContextActionService")
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local camera = workspace.CurrentCamera
local cameraOffset = Vector3.new(2, 2, 8)
local player = Players.LocalPlayer

player.CharacterAdded:Connect(function(character)

	local humanoid = character:WaitForChild("Humanoid")
	local rootPart = character:WaitForChild("HumanoidRootPart")
	humanoid.AutoRotate = false

	local cameraAngleX = 0
	local cameraAngleY = 0

	local function playerInput(actionName, inputState, inputObject)
		-- Calculate camera/player rotation on input change
		if inputState == Enum.UserInputState.Change then
			cameraAngleX = cameraAngleX - inputObject.Delta.X
			-- Reduce vertical mouse/touch sensitivity and clamp vertical axis
			cameraAngleY = math.clamp(cameraAngleY-inputObject.Delta.Y*0.4, -75, 75)
			-- Rotate root part CFrame by X delta
			rootPart.CFrame = rootPart.CFrame * CFrame.Angles(0, math.rad(-inputObject.Delta.X), 0)
		end
	end
	ContextActionService:BindAction("PlayerInput", playerInput, false, Enum.UserInputType.MouseMovement, Enum.UserInputType.Touch)

	RunService.RenderStepped:Connect(function()
		if camera.CameraType ~= Enum.CameraType.Scriptable then
			camera.CameraType = Enum.CameraType.Scriptable
		end
		local startCFrame = CFrame.new((rootPart.CFrame.Position)) * CFrame.Angles(0, math.rad(cameraAngleX), 0) * CFrame.Angles(math.rad(cameraAngleY), 0, 0)
		local cameraCFrame = startCFrame:ToWorldSpace(CFrame.new(cameraOffset.X, cameraOffset.Y, cameraOffset.Z))
		local cameraFocus = startCFrame:ToWorldSpace(CFrame.new(cameraOffset.X, cameraOffset.Y, -10000))
		camera.CFrame = CFrame.new(cameraCFrame.Position, cameraFocus.Position)
	end)
end)

local function focusControl(actionName, inputState, inputObject)
	-- Lock and hide mouse icon on input began
	if inputState == Enum.UserInputState.Begin then
		UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
		UserInputService.MouseIconEnabled = false
		ContextActionService:UnbindAction("FocusControl", focusControl, false, Enum.UserInputType.MouseButton1, Enum.UserInputType.Touch, Enum.UserInputType.Focus)
	end
end
ContextActionService:BindAction("FocusControl", focusControl, false, Enum.UserInputType.MouseButton1, Enum.UserInputType.Touch, Enum.UserInputType.Focus)

local Open = false

UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode["M"] then
		Open = not Open
		if Open then
			--here I don't know how to make the mouse move freely after pressing this key
		else
			--Pressing again to lock the mouse again to move the camera without having to right click
		end
	end	
end)

Well I did this, but I think it’s the right thing to do:

UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode["M"] then
		Open = not Open
		if Open then
			repeat
				UserInputService.MouseBehavior = Enum.MouseBehavior.Default
				UserInputService.MouseIconEnabled = true
				wait()
			until UserInputService.MouseBehavior == Enum.MouseBehavior.Default and UserInputService.MouseIconEnabled == true
		else
			repeat
				UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
				UserInputService.MouseIconEnabled = false
				wait()
			until UserInputService.MouseBehavior == Enum.MouseBehavior.LockCenter and UserInputService.MouseIconEnabled == false
		end
	end	
end)

But I think there is something missing in this part of here:

UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
UserInputService.MouseIconEnabled = false
ContextActionService:UnbindAction("FocusControl", focusControl, false, Enum.UserInputType.MouseButton1, Enum.UserInputType.Touch, Enum.UserInputType.Focus)
