I need help accessing player from module script and a actual script?

So, I made a Module script inside of a actual script(not local script.) I am trying to clone a folder with Values inside of it into an actual player through two different scripts. Module and Acutal Script?

Here's the code for the Module..

local Module = {}

function Module.CreateFolder()
    local plr

    local Folder = Instance.new("Folder", plr)
    Folder.Name = "Folder"

    Instance.new("IntValue", Folder).Name = "Tokens"
    Instance.new("IntValue", Folder).Name = "Codes"
    Instance.new("StringValue", Folder).Name = "Trade"
    Instance.new("BoolValue", Folder).Name = "BetaTester"
    Instance.new("BoolValue", Folder).Name = "Exploiter"
    Instance.new("BoolValue", Folder).Name = "Loaded"
    Instance.new("BoolValue", Folder).Name = "Accept"
    Instance.new("BoolValue", Folder).Name = "AFK"

end

return Module

Here's the actual script..

local Folder = require(script.Folder)

game.Players.PlayerAdded:Connect(function(plr)
    Folder.CreateFolder()
end)

I thought this would work because of me thinking that I can make my code as neat as possible, but it didn't put the folder into the player.

Question: How can I still keep the module script and access the function "plr" without the script doing things that I didn't want it to do?
