Is there a way to add your own melting recipes for the jumbo furnace mod?

[ivan009god]

hello everyone
I've only recently started working with scripts in kubejs, so I'm not good at it yet.
Right now I need to create a custom melting recipe JUST for kubejs, but I can't do that.
kubes does not give any errors, but the recipe in the game does not work.
Can anyone help me?
Minecraft version: 1.20.1
Here is the code itself:

event.custom({
type: "jumbofurnace:jumbo_smelting",
ingredients:
[
{
type: "forge:nbt",
item: "minecraft:iron_nugget",
count: 27
},
],
results: [
{ item: "minecraft:iron_ingot" }
],
