My Top Down Camera Script is being buggy and i dont know what to do, Help?

I am trying to make a top down camera script yet it is not working. The error is on line 13 and the error message is:

Players.adieking1.PlayerScripts.CameraScript:13: invalid argument #2 (Vector3 expected, got CFrame)

Script:

game:GetService("ControllerService"):ClearAllChildren()

repeat wait() until game.Players.LocalPlayer.Character
local char = game.Players.LocalPlayer.Character
local cam = game.Workspace.CurrentCamera

cam.CameraType = Enum.CameraType.Scriptable
cam.FieldOfView = 70

Spawn(function()
while true do
		game:GetService("RunService").RenderStepped:wait()
		cam.CoordinateFrame = CFrame.new(char.HumanoidRootPart.Position + Vector3.new(5, 10, -5) , char.HumanoidRootPart.Position)+ CFrame.Angles(0,0,0)-- Please note that the Angles part is for after the script works so I can adjust it then.
	end
end)

Please ask if you need any more information.

Use multiplication to add up two CFrames:

game:GetService("ControllerService"):ClearAllChildren()

repeat wait() until game.Players.LocalPlayer.Character
local char = game.Players.LocalPlayer.Character
local cam = game.Workspace.CurrentCamera

cam.CameraType = Enum.CameraType.Scriptable
cam.FieldOfView = 70

spawn(function()
	while true do
		game:GetService("RunService").RenderStepped:wait()
		local pose = char.HumanoidRootPart.Position + Vector3.new(5, 10, -5)
		local lookAt = char.HumanoidRootPart.Position
		cam.CFrame = CFrame.new(pose , lookAt) * CFrame.Angles(0,0,0)-- Please note that the Angles part is for after the script works so I can adjust it then.
	end
end)
