How can i pass a variable back to client?

[Y_Boss]

Hello to this community.How can i pass a variable back to my client script?I give the server the ped with this :

RegisterNetEvent("house:OpenStorage")
AddEventHandler("house:OpenStorage",function()
TriggerEvent('chatMessage','test')
local id = TriggerServerEvent("loaf_housing:giveid")
exports["mf-inventory"]:openOtherInventory(id)
end)

RegisterNetEvent("house:createStorage")
AddEventHandler("house:getIdentity",function()
	local ped = GetPlayerPed()
	TriggerServerEvent("house:makeStorage",ped)
end)

and the server prints the steamID correctly…now i want to give this steam id back to my client so it can open his unique inventory.Any suggestions? this is the server code aswell

RegisterServerEvent('house:makeStorage')
AddEventHandler('house:makeStorage', function(ped)
local xPlayer = ESX.GetPlayerFromId(source)
local identifiers = GetPlayerIdentifiers(source,2)


id = table.unpack(identifiers)

print(tostring(id))


local uniqueIdentifier =  id      -- Unique identifier for this inventory.
local inventoryType = "inventory"                                 -- Inventory type. Default is "inventory", other types are "shop" and "recipe".
local inventorySubType = "housing"                                -- Inventory sub-type, used to modify degrade modifiers by the config table.
local inventoryLabel = "house_storage"                            -- The inventorys UI label index (which will pull the translation value).
local maxWeight = 250.0                                           -- Max weight for the inventory.
local maxSlots = 50                                               -- Max slots for the inventory.
local items = exports["mf-inventory"]:createInventory(uniqueIdentifier,inventoryType,inventorySubType,inventoryLabel,maxWeight,maxSlots,items)


end)

Use ESX.RegisterServerCallback on Serverside
and
use ESX.TriggerServerCallback Clientside

Examples how to use it are on the Linked Pages
