[Resolved]Only activate cooldown after complete use duration of the item

[tulip iron]

I currently have an item which need to be used for a bit to activate its ability, the cooldown however, starts as soon as the item is interacted with.

Item Json:

{
    "format_version": "1.21.30",
    "minecraft:item": {
        "description": {
            "identifier": "vcs:laser_blazer",

                "category": "equipment",
                "group": "itemGroup.name.sword"
            }
        },

            "minecraft:icon": {
                "textures":{
                    "default":"laser_blazer"
            }
            },
            "minecraft:custom_components":[

            "minecraft:can_destroy_in_creative": false,

            "minecraft:use_animation":{

            },

                "duration":120
            },
            "minecraft:durability": {
                "max_durability": 2064
            },
            "minecraft:repairable": {
                "repair_items": [
                    {
                        "items": ["vcs:void_steel_ingot"],
                        "repair_amount": 517
                    }
                ]
            },
            "minecraft:hand_equipped":true,
            "minecraft:tags":{
                "tags":["vcs:sword"]
            }

    
        
}
    }
}

Script Event:```
onCompleteUse({source,itemStack}) {
if(itemStack.keepOnDeath === false){
const inventory = source.getComponent("inventory").container;
itemStack.keepOnDeath = true
inventory.setItem(source.selectedSlotIndex, itemStack)
}
source.addEffect("resistance",1200,{
amplifier: 2,
showparticles: false
})
source.addEffect("regeneration",1200,{
amplifier: 3,
showparticles: false
})
source.runCommand("playanimation @s animation.power_up a 0 query.is_moving")
source.runCommand("particle vcs:power_up ~ ~ ~")
source.startItemCooldown("vc:power",2400)
}

Nevermind I solved my own problem 🤦‍♂️
