How do I cause the camera to return to normal on mouseclick?

I'm using a script which fixes the camera at a certain location, and all works well with that. What I don't know, though, is how to return the camera to normal when the start button is pressed. How would this be achieved? Thanks in advance.

The script:

local cam = workspace.CurrentCamera
local CameraLocation = Vector3.new(-22.5, 35.5, -58.5)
local CameraDirection = Vector3.new(-8, 4.5, -92)

cam.CameraType = Enum.CameraType.Scriptable

game["Run Service"].RenderStepped:connect(function()
    cam.CoordinateFrame = CFrame.new(CameraLocation,CameraDirection)
end)


--[[ Title Screen Script ]]


function onClicked()
    titlescreen:Destroy()
    cam.CameraType = Enum.CameraType.Fixed
end

titlebutton.MouseButton1Down:connect(onClicked)
