Curios Slot Icons

[JUGGERNAUTLMG]

I am trying to add slots for a Helmet, Chestplate, Leggings, and Boots. Not all of those categories seem to have icons from curios, so I was wondering what to put in the icon part of the config. I am thinking to use Minecraft's armour slot icons but I don't know what to type to access them properly in the config.
