How do I save inventory items? I have a script that saves leaderstats and I want to edit it in.

I need help saving inventory items. I can save the leader board, but not their inventory items. Here is the script I'm using, I want it to also save inventory items but idk how.

 function onPlayerEntered(player)
 wait(3)
 player:WaitForDataReady()
repeat wait() until player:FindFirstChild("leaderstats")
 if player.DataReady then
 if player:findFirstChild("leaderstats") then
 local score = player.leaderstats:GetChildren()
 for i = 1,#score do
 local ScoreLoaded = player:LoadNumber(score[i].Name)
 wait()
 if ScoreLoaded ~= 0 then
 score[i].Value = ScoreLoaded
 end
end
 end
 end
 end
 
 function onPlayerLeaving(player)
 if player:findFirstChild("leaderstats") then
 local score = player.leaderstats:GetChildren()
 for i = 1,#score do
player:SaveNumber(score[i].Name,score[i].Value)
end
end
end
 
game.Players.PlayerAdded:connect(onPlayerEntered)
 game.Players.PlayerRemoving:connect(onPlayerLeaving)

Thank For Help.

You don't save the inventory items itself. How does the user obtain items? If its from a shop or something, use data store to save whether or not they have unlocked that item, and to give it to them when they join
