Script Not Taking Randomly Maps?

i trying to make intermission script. with maps. it's works. and map randomly works but the problem is that. it's not taking randomly after the map ended. this script works with rounds. it's works but it's not taking Random Maps Like Forest map Or Garden Map And It's only Choice The Same Map. and i want it to make it randomly maps. sorry but i starting to be really advanced scripter but i don't know what it's the problem of it.. there some more i need to learn :)

this is short version of it.

local minigameModule = {
    gameRunning = false,
    playersAlive = {},
    currentMap = nil
}

local waitForChild = game.WaitForChild
local findFirstChild = game.FindFirstChild

-- Modules

local settingsModule = require(waitForChild(script, "Settings"))
local onWin = (function()
    local onWinModule = findFirstChild(script, "OnWin")

    if onWinModule then
        local onWinFunction = require(onWinModule)

        if type(onWinFunction) == "function" then
            return onWinFunction
        end
    end
end)()

local remoteEvent = waitForChild(game:GetService("ReplicatedStorage"), "Event")
local mapsStorage = waitForChild(game:GetService("ServerStorage"), "Maps"):GetChildren()

local playersService = game:GetService("Players")

function minigameModule.isPotentialGame()
    return playersService.NumPlayers >= settingsModule.minimumPlayers
end

function minigameModule:chooseMap()
    local chosenMap = mapsStorage[#mapsStorage]:Clone()
    if findFirstChild(chosenMap, "Spawns") then
        chosenMap.Parent = workspace
        chosenMap:MakeJoints()
        self.currentMap = chosenMap
        return chosenMap;
    end
end

i don't think needs more but this is the full version of it,
