Vault loot tables

I want to make the vault loot table different, where a heavy core is more likely from ominous vaults and ominous bottles are more likely from normal vaults
  "type": "minecraft:vault",
  "pools": [
    {
      "rolls": 0,
      "entries": [
        {
          "type": "minecraft:item",
          "name": "minecraft:ominous_bottle",
          "weight": 1,
          "quality": 1
        },
        {
          "type": "minecraft:loot_table",
          "children": [],
          "value": "minecraft:spawners/trial_chamber/key",
          "weight": 3,
          "quality": 1,
          "functions": []
        }
      ]
    }
  ]
}```
this is my current one with misode, is this right? and how would i do the ominous variant of this
