How can I send data from server to module?

I’m making a trading system and I found a tutorial that uses tools. But my games uses data in tables for each player and stuff, this is the module from the tutorial on how he accessed a players tools:

local config = {}


-------Settings you can change-------
config.MaxSlots = 9
config.TimeBeforeTradeConfirmed = 10
-------------------------------------


--Funcion for getting all the tools a player has
function config.GetTools(plr)
	
	local plrTools = plr.Backpack:GetChildren()

	local toolEquipped = plr.Character:FindFirstChildOfClass("Tool")
	if toolEquipped then
		table.insert(plrTools, toolEquipped)
	end

	return plrTools
end

return config

But my game uses data which is only in this server script I made:

local data = {}

--load player data
local function loadData(player)
	local success = nil
	local playerData = nil
	local attempt = 1

	repeat
		success, playerData = pcall(function()
			return dataBase:GetAsync(player.UserId)
		end)

		attempt += 1
		if not success then
			warn(playerData)
			task.wait()
		end
	until success or attempt == 3

	if success then
		if not playerData then--give default data if they're new
			playerData = {
				["Gems"] = 0,
				["SelectedTowers"] = {"Cameraguy"},
				["OwnedTowers"] = {"Cameraguy"},
				["MaxTowers"] = 5,
				["RedeemedCodes"] = {}
			}
			beamEvent:FireClient(player)
		end
		
		data[player.UserId] = playerData

So my question is, how can I send this data to the module so the module script can access it and edit the module script return it. Any help is appreciated, thanks!

You can just create a function within the module script that recieves parameters. The function can then return the modified function to the normal script

For example:
Server Script:

local Info = {"Apples", "Bananas"}

local Module = require(script.Parent.ModuleScript)
Info = Module.AddPear(Info)

print(Info) -- Apples, Bananas, Pear

Module Script:

local module = {}

function module.AddPear(Info)
    table.insert(Info, "Pear")
    return Info
end

return module
