Making arms face the camera

So I’m trying to make the character’s arms face the camera, but because I’m inexperienced with this type of stuff of course it doesn’t work :sob:
Here’s a video: https://streamable.com/0fstb1

game:GetService("RunService").RenderStepped:Connect(function()
    RootPart.FakeRoot.C1 = CFrame.new(Vector3.new(0,0,0),-Camera.CFrame.LookVector)
end)

Anyone familiar with this type of stuff?

You could do something similliar to that:

local players = game:GetService("Players");
local localPlayer = players.LocalPlayer;
local mouse = localPlayer:GetMouse()

function render_Step(dt)
   FakeRoot.C1 = CFrame.new(workspace.CurrentCamrea.CFrame.p, mouse.Hit.p) -- Sets it's position to the camera's position, and making it look towards the mouse's position vector
end

runService.RenderStepped:Connect(render_Step)
