How to spin a simple parts with torque physics force?

I am familiarizing myself with physics in Roblox. I want to use physics to have a small and simple ball spin on itself, so I have performed the following procedure. I have inserted a part with ball shape and enabled custom physics and anchored it. I have added an attachment inside this part, and linked a torque force to this attachment (with Torque = Vector3.new(10,10,10)). My ball is not spinning/rotating, it looks like nothing is happening at all. What am I missing?

To do a spin I'd honestly just use a BodyAngularVelocity.
