Properly show enchantment for advancement icon 1.20.5

Hi, updating advancement .json to 1.20.5
"display": {
    "icon": {
      "id": "minecraft:golden_shovel",
      "nbt": "{Enchantments:[{id:\"minecraft:silk_touch\"}]}"
    },

I was reading but couldn't figure out exactly how I would convert it properly? thanks!
