Lua Script summon

[Azerty]

I'm trying to make this script work, I need it to only summon the amount defined in maxMonster, but it summons the monsters infinitely, could anyone help me? And I also need you to summon 2 different monsters, you can use Demon as an example

local function getRandomPosition(minPosition, maxPosition)
    local randomX = math.random(minPosition.x, maxPosition.x)
    local randomY = math.random(minPosition.y, maxPosition.y)
    local randomZ = math.random(minPosition.z, maxPosition.z)
    return Position(randomX, randomY, randomZ)
end

local function summon()
    local boss = false
    local bossId
    local count = 0
    local positionCenter = Position(33710, 31634, 14)
    local spectators = Game.getSpectators(positionCenter, false, false, 10, 10, 10, 10)
    local maxMonster = 3

    for _, creature in pairs(spectators) do
        if creature:isMonster() then
            if creature:getName():lower() == "goshnar's megalomania" then
                boss = true
                bossId = creature:getId()
            elseif creature:getName():lower() == "Greater Splinter of Madness" then
                count = count + 1
            end
        end
    end

    if boss and count < maxMonster then
        local minPosition = Position(33703, 31628, 14)
        local maxPosition = Position(33717, 31640, 14)
        local randomPosition = getRandomPosition(minPosition, maxPosition)
        Game.createMonster("Greater Splinter of Madness", randomPosition):registerEvent("fieryHearts")
    end

    if boss and count < maxMonster then 
        local randomDelay = math.random(40, 60) * 1000
        addEvent(summon, randomDelay)
    end
end
