"You must AddTorque to the component of the Blueprint that is simulating physics."

so I’ve been trying to make some first person flying game and when I asked someone about why I couldn’t find AddTorque, they told me this. “You must AddTorque to the component of the Blueprint that is simulating physics.” I’m using the flying blueprint, and I’m pretty new so I don’t know what component of the blueprint is simulating physics. thank you for the help!
