How to add Exp boost time to otclient?

[sevengym]

I'm trying to add exp boost time to otclient. Any tips how to do it properly? Thats my Exp boost script. I added this in skills.lua onExpBoostChange = onExpBoostChange, and also this onExpBoostChange(player, player:getStorageValue()) and then i made a function with storage. I also tried adding a new function in compat.lua so i don't need to use storage. Nothing seems to work so far. Ofc i added the button in skills.otui

local boostStorage = 693690
local boostDuration = 18000 -- 5 hours in seconds

function onUse(cid, item, fromPosition, itemEx, toPosition)
    local player = Player(cid)
    local currentBoostEnd = player:getStorageValue(boostStorage)
    local currentStamina = player:getStamina()

    if currentBoostEnd >= os.time() and currentStamina > 14 * 60 then
        player:sendTextMessage(MESSAGE_STATUS_CONSOLE_ORANGE, "You already have an EXP boost active!")
        return true
    end

    local newBoostEnd = os.time() + boostDuration

    if currentStamina <= 14 * 60 then
        local remainingStaminaTime = currentStamina * 60
        newBoostEnd = os.time() + remainingStaminaTime
    end

    player:setStorageValue(boostStorage, newBoostEnd)
    player:sendTextMessage(MESSAGE_STATUS_CONSOLE_ORANGE, "Your 5 hours EXP boost has started! You will gain 25% extra experience.")
    item:remove(1)
    return true
end

its not reliable to use onExpBoostChange = onExpBoostChange because thats a scripted boost not tibia basic exp boost (stamina) so i would use opcodes to send info [TUTORIAL MODS]- Creating Modules with Extended Opcode (https://otland.net/threads/tutorial-mods-creating-modules-with-extended-opcode.270062/)
