How can I get all keys and values of a data store in table form?

I want to read all values of a data store and create a gui for them, but I’m having trouble reading the data store. Here’s the script:

local success, passed = pcall(function()
			rankedStore:GetAsync()
		end)
		
		if success then
			for i, name in pairs(passed) do
				addGui:FireClient(plr,name)
				print("ui request sent")
			end
		end

I don’t think it can read the data store because I didn’t put a key as the argument, but I want to put all keys into a table. How could I do this?

is this the whole script if not can i see it?

Here’s the whole script:

local Players = game:GetService("Players")

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local addGui = ReplicatedStorage.FireAddGUI

local DataStoreService = game:GetService("DataStoreService")
local rankedStore = DataStoreService:GetDataStore("RankedStore")

Players.PlayerAdded:Connect(function(plr)
	if plr:GetRankInGroup(11635716) >= 254 then
		local success, passed = pcall(function()
			rankedStore:GetAsync()
		end)
		
		if success then
			for i, name in pairs(passed) do
				addGui:FireClient(plr,name)
				print("ui request sent")
			end
		end
	end
end)

try this

rankedStore:GetAsync(plr.UserId)

sorry for the late reply

I want to get all keys and values of the data store, not just the key and value of the data store, not just the one of the player that joined. What I’m asking is is there a way to get all keys and values of the data store in table form?
