Modify an item to be a food

[plavie]

I want to customize an item : to turn it into food. Firstly i tryed to do it my self but i failed. Then, I tryed to use the excate same exemple provid by the wiki but it fails. I tryed to find a solution but it seems that their is only old solution, I am in 1.21.1 in NeoForge.
The exemple is :

ItemEvents.modification(event => {
event.modify('minecraft:diamond', item => {
item.foodProperties = food => {
food.hunger(2)
food.saturation(3)
food.fastToEat()
}
})

event.modify('minecraft:pumpkin_pie', item => {
item.foodProperties = null // make pumpkin pies inedible
})
})
