Is there a way to place a object in the hand instead of the contorllers

Hey, I am trying to make a shooting range application, and I wish for the weapon in the game to be in the place of the controller. I don't have a beefy computer and meet the bare minimum, and this was the only way I code for Quest 3 at the moment, which is through the Meta Spatial SDK. I see in the spatial Editor there is an AvatarBody Component that allows you to attach things to it, but I am reading that it allows you to use it in the sense of making your own Playable Avatar and using that to attach things to your avatar. there are no samples out there yet anyone figured out how to replace the controller model with another object yet
