Detecting minimum height as a requirement for attribute effect inside of an enchantment

I've been struggling to figure out exactly where to slot in the requirements for the attribute effects for this enchantment, please point out my (probably) painfully obvious mistake ```{
  "anvil_cost": 4,
  "description": {
    "text": "Slipstream"
  },
  "exclusive_set": "ambideer:shrinking",
  "effects": {
    "minecraft:attributes": [
      {
        "amount": {
          "type": "minecraft:linear",
          "base": 0.25,
          "per_level_above_first": 0.25
        },
        "attribute": "minecraft:flying_speed",
        "id": "ambideer:enchantment.aerodynamic.flying_speed",
        "operation": "add_multiplied_base"
      }
    ]
  },
  "requirements": {
    "condition": "minecraft:location_check",
    "predicate": {
      "position": {
        "y": {
          "min": 120
        }
      }
    }
  },
  "max_cost": {
    "base": 10,
    "per_level_above_first": 5
  },
  "max_level": 10,
  "min_cost": {
    "base": 10,
    "per_level_above_first": 5
  },
  "slots": [
    "saddle",
    "any"
  ],
  "supported_items": "#minecraft:harnesses",
  "weight": 10
}
