Granting gear to player upon join - how to wait until the player is fully loaded?

1. I successfully step through this method to grant joining players gears.
2. But I'm guessing the rest of character loading is replacing the backpack, so the player never gets the gear
3. What's the proper way to run scripts after the basic player backpack setup is done?

local dataSource = require(game.ServerScriptService.BehaviorLogic)

function playerJoined(player)
	local gear = dataSource["GetInfo"](player, "GetGear")
	SetupGear(player, gear)
end

local ins = game:GetService("InsertService")

function SetupGear(player, gear)
	--wait(5) uncommenting this line makes it work
	for _, assetId in ipairs(gear) do

		print("Granting"..tostring(assetId))
		local tool = ins:LoadAsset(assetId):GetChildren()[1]
		print(tool)
		tool.Parent = player.Backpack
	end
end

game.Players.PlayerAdded:Connect(playerJoined)

Add this line to ensure the character is fully loaded.

player.CharacterAdded:Wait()

You can use game.Loaded:Wait() to wait until the game is completely loaded, you should put this in a local script, then after that line you can fire a remote event to the server and give them the tool then.

if you want to go with the character, then use repeat wait() until player.Character

Alternatively you can just add a wait(5) or more seconds before you give the tool.

Also the player joined function should be beneath the setup tools function.
