JSON Model Display Tag (Solved)

I am trying to make my custom blocks render in the inventory like the rest of the blocks in the game. I believe that I need to add the below display code to my JSON file, but I'm not sure where to add it. 

The display code is as follows:

    "display": {
       "fixed": {
           "rotation": [ 0, 90, 0 ],
           "translation": [ 0, 0, 0 ],
           "scale": [ 0.5, 0.5, 0.5 ]
       }
   },

Any help with this would be greatly appreciated, and I am happy to make any clarifications necessary.
