How do i make my camera tween back to the player???

Ok so, i have already made a script where i made a region3.

When you are inside that region3 the camera will tween to a 2d view. Now, i made so that when you walk outside of the region the cameratype will be custom which resets the camera back to normal.

But i want it to tween back to the camera smoothly like it did when i entered the region.

Does anyone here know how to tween a camera back?

and i dont want it to copy the location that it was and tween it back to that location since my character is able to walk out from other parts of the region!

Here is my code so far!

local CutCam = game.Workspace.CameraForCutscene.CutsceneCamera

local Found = false

local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:WaitForChild("Humanoid")

local camera = game.Workspace.CurrentCamera

local SoundregionsFolder = game.Workspace.Regions

local OrientationPart = game.Workspace.CameraForCutscene.OrientationPart

game:GetService("RunService").Stepped:Connect(function()

    CutCam.CFrame = CFrame.new(player.Character.HumanoidRootPart.Position) * CFrame.new(1,1,3)
    CutCam.Orientation = player.Character.HumanoidRootPart.Orientation + Vector3.new(20,0,0)
end)



local cameraCFrame = workspace.CurrentCamera.CFrame

local TS = game:GetService("TweenService")



while wait(0.1) do



    local TweenBackInfo = TweenInfo.new(1, Enum.EasingStyle.Cubic, Enum.EasingDirection.Out, 0)
    local Back = {CFrame = cameraCFrame}
    local TweenBack = TS:Create(camera,TweenBackInfo,Back)

    for i, v in pairs(SoundregionsFolder:GetChildren())do

        Found = false

        local region = Region3.new(v.Position - (v.Size/2),v.Position + (v.Size/2))

        local Parts = game.Workspace:FindPartsInRegion3WithWhiteList(region, game.Players.LocalPlayer.Character:GetDescendants())


        for _, part in pairs(Parts) do

            if part:FindFirstAncestor(game.Players.LocalPlayer.Name) then
                print("Player Was Found")
                Found = true
                break
            else
                Found = false
                print("Player Was Not Found")
                break
            end
        end

        if Found == true then
            print("Player Was Found")
            camera.CameraType = Enum.CameraType.Scriptable
            local TweeningInfoCutScene = TweenInfo.new(1, Enum.EasingStyle.Cubic, Enum.EasingDirection.Out, 0)
            local CameraCutSceneCF = {CFrame = CutCam.CFrame}
            local TweenCameraCutScene = TS:Create(camera,TweeningInfoCutScene,CameraCutSceneCF)     
            TweenCameraCutScene:Play()  
            break
        end

        if Found == false then
            print("Player Was Not Found")


            camera.CameraType = Enum.CameraType.Custom


        end


    end

end
