How would I properly save and retrieve tables from a DataStore?

Here are the Variables I assigned:

local ds = game:GetService("DataStoreService")
local ds1 = ds:GetDataStore("Vrank")
local ds2 = ds:GetDataStore("ARank")

local owner
local admin = {}
local votePerms = {}

This is what I used to retrieve all the data saving into that table:

local s, e = pcall(function()
    for i, v in ipairs(ds1:GetAsync("VoteStarters",votePerms)) do
        table.insert(votePerms, #votePerms+1, v)
    end
end)

Finally, the code that is supposed to insert and save new data into the table:

if args[2] then
    if game.Players:FindFirstChild(args[2]) then
        local newRank = game.Players:FindFirstChild(args[2]).UserId
        table.insert(votePerms, #votePerms+1, newRank)
        local s, e = pcall(function()
            ds1:SetAsync("VoteStarters",votePerms)
        end)
    end
end

Thank you for taking the time to read this!
