Do custom Smithing_Trim recipes work

I've made a super simple custom recipe that's just 
  "type": "minecraft:smithing_trim",
  "base": "#minecraft:trimmable_tool",
  "addition": "#minecraft:trim_materials",
  "template": "#minecraft:trim_templates"
}```

the custom tag is just:
```{
  "values": [
    "#minecraft:swords",
    "#minecraft:pickaxes",
    "#minecraft:axes",
    "#minecraft:shovels",
    "#minecraft:shovels",
    "minecraft:trident",
    "minecraft:mace",
    "minecraft:crossbow",
    "minecraft:bow"
  ]
}```

And even like replacing the custom tag with just chicken or smth the recipe doesn't work, so is the crafting type something like dye where you just can't make custom ones?
