How do i save the players that are banned from the game?

local DatastoreService = game:GetService("DataStoreService")
local ds = DatastoreService:GetDataStore("BanList")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local event1 = ReplicatedStorage.AdminGui:WaitForChild("Ban")
local event2 = ReplicatedStorage.AdminGui:WaitForChild("Unban")

local Players = game:GetService("Players")

local bannedpeople = {}

ds:GetAsync(bannedpeople)

game.Players.PlayerAdded:Connect(function(plr)
    if table.find(bannedpeople, plr.UserId) then
        wait(0.2)
        plr:Kick("You are permanently banned from the game.")
        print("autoban")
    end
end)

local function Banned(admin, username, reason)
    local bannedplayer = Players:FindFirstChild(username)
    if bannedplayer ~= nil then
        game.Players:FindFirstChild(bannedplayer):Kick(reason)
        table.insert(bannedpeople, bannedplayer.UserId)
        ds:SetAsync(bannedpeople)
        print("banned")
    end
end

local function Unbanned(admin, username, reason)
    local unbannedplayer = Players:FindFirstChild(username)
    if unbannedplayer ~= nil then
        if table.find(bannedpeople, unbannedplayer.UserId)then
            table.remove(bannedpeople, table.find(bannedpeople, unbannedplayer.UserId))
            ds:SetAsync(bannedpeople)
            print("unbanned")
        end
    end
