Moon Animator wont let me animate seperate parts of a model

I want to animate two parts of a model (in this case a sword and sheathe) separately, while still being apart of the same model, like how a humanoid rig’s arms can be moved without moving the entire rig.

The only thing I can change is the CFrame of the entire model.

I’m kinda stumped. Any help is appreciated.

I dont use moon but the reason you can animate the different parts of a rig is probably because its rigged.

are your parts riged?

How do I rig parts?
