Skinchanger Problems

[Lutobtw]

Hello there, I have a Problem with my bproof Vest Script. I to change the color of the bproof but I don’t know how. Here is my current code

RegisterNetEvent('westen:bproof')
AddEventHandler('westen:bproof', function()

    useVest()

end)

function useVest()
    local playerPed = PlayerPedId()
    local lib = 'anim@heists@narcotics@funding@gang_idle'
    local anim = 'gang_chatting_idle01'
    ESX.Streaming.RequestAnimDict(lib, function()
        TaskPlayAnim(playerPed, lib, anim, 8.0, -8.0, -1, 0, 0, false, false, false)
        RemoveAnimDict(lib)
    end)
    Citizen.Wait(0)
    DisableAllControlActions(0)
    ClearPedTasks(playerPed)
    ESX.ShowNotification("Du benutzt eine ~b~kugelsichere Weste")

    Wait(1000)
    SetPedArmour(playerPed, 100)
    TriggerEvent('skinchanger:change', 'bproof_1', 20)
    ESX.ShowNotification("~g~Kugelsichere Weste angezogen")
end

I would be happy if someone could help me
