Use SteamVR and Vive controller or tracker ONLY for position tracking, no headset

I am VERY new to Unity and integration with SteamVR, so any help would be appreciated – I want to use an HTC Vive controller or tracker for position tracking only, and without using the headset (aside from plugging it in and leaving it on the ground). I just want to be able to get x,z coordinates while someone walks back and forth in a room, but without displaying any VR content or using the headset at all. I have a Scene in Unity that is basically one large plane, and my thought is to make the controller a Game Object and then attach a script to it that’s continuously writing out its position, velocity, and a time stamp to something like a .txt or .csv, but I’m stuck on the first step of adding it to my Scene.

Use [CameraRig] prefab as intended and place your logging script to hand anchors
