Incomplete Smithing Transformation

Are there any other prerequisites I need to meet to make this smithing table transformation applicable, it doesn't do anything atm { "type": "minecraft:smithing_trim", "template": { "item": "minecraft:netherite_upgrade_smithing_template" }, "base": { "tag": "minecraft:enchantable/durability" }, "addition": { "item": "minecraft:gold_ingot" } } { "asset_id": "minecraft:gild", "description": { "translate": "trim_pattern.minecraft.gild" }, "template_item": "minecraft:netherite_upgrade_smithing_template" }
