Change menu graphic material based on which controller type is being used in Steam VR.

I have an in game/vr computer screen showing the controller settings in my project. I have different graphics to put on this screen based on when the user is running the game with a Valve Index controller or a Vive (pro) Controller. Each graphic is set with its own material which I can swap but what I need to know is how the build recognizes which controller is being used?

SteamVR and Unity OpenVR must have a way of telling which controller is in use as it automatically swaps out the model of the controller but I don't know how to tap into that recognition so I can swap my graphic.

I have been looking at SteamVR_RenderModel.cs (mostly around line 145-167.) but I can't seem to figure it out and I don't even know if I'm looking in the right place? (https://github.com/ValveSoftware/steamvr_unity_plugin)

Do any of you know how to do this?

I have found the IVR system but the documentation is confusing? Can any one help me understand how I would change out player instructions based on what controller is in use? It seems like this would be a common need but I have not found any information clarifying the concept while scouring the web for a solution.

This is as far as I have made it. Its not much.

 using UnityEngine;
 using Valve.VR;
 
 public class ControllerBasedRenderer : $$anonymous$$onoBehaviour
 {
     public Renderer Object;
     public $$anonymous$$aterial default$$anonymous$$aterial;
     public $$anonymous$$aterial vive$$anonymous$$aterial;
     public $$anonymous$$aterial index$$anonymous$$aterial;
     public $$anonymous$$aterial oculus$$anonymous$$aterial;
 
     void OnEnable()
     {
         //Subscribe to the event that is called by S$$anonymous$$mVR_Render$$anonymous$$odel, when the controller and it's associated material has been loaded completely.
         S$$anonymous$$mVR_Events.Render$$anonymous$$odelLoaded.Listen(OnControllerLoaded);
     }
 
 
     void Start() //$$anonymous$$eep the script accessible to turn off/on in the inspector.
     {
        
     }
 
     public void Update$$anonymous$$aterial($$anonymous$$aterial new$$anonymous$$aterial)
     {
 
         //How can I find if Vive or if index/knuckles?
         //if(controler index is the vive?){
         Object.material = vive$$anonymous$$aterial;
 
         //if its an index controller in use?
         //Object.material = index$$anonymous$$aterial;
 
         //if its an oculas touch?
         //Object.material = oculus$$anonymous$$aterial;
 }
 
     void OnControllerLoaded(S$$anonymous$$mVR_Render$$anonymous$$odel controllerRender$$anonymous$$odel, bool success)
     {
         Update$$anonymous$$aterial(default$$anonymous$$aterial);
     }
 
     void OnDisable()
     {
         //Unsubscribe to the event if this object is disabled.
         S$$anonymous$$mVR_Events.Render$$anonymous$$odelLoaded.Remove(OnControllerLoaded);
     }
 
 }
