Loot Tables missing looting enchant field?

I'm working on updating Jragon014's tempest box (with his permission, I went to update the mob loot-tables but couldn't find what field I use for looting enchant count differences?
This is the original code? I am using misode generator to look but can't find it under function or condition
    "pools": [
        {
            "rolls": 1,
            "entries": [
                {
                    "type": "item",
                    "weight": 1,
                    "name": "minecraft:rotten_flesh",
                    "functions": [
                        {
                            "function": "set_count",
                            "count": {
                                "min": 1,
                                "max": 6
                            }
                        },
                        {
                            "function": "looting_enchant",
                            "count": {
                                "min": 0,
                                "max": 1
                            }
                        }
                    ]
                },
