What do I use in order to get the assets?

So, what I'm trying to do is GetObjects, but it says "GetObjects" is not a member of DataModel. And I am not sure on what exactly to use to get them. Here it is.

game:GetObjects("rbxassetid://103727739")[1].Parent = game.Workspace
wait(0.5)
game.Workspace.Towers:MoveTo(game.Players.LocalPlayer.Character.Torso.Position + game.Players.LocalPlayer.Character.Torso.CFrame.lookVector* 30)
wait(2)
x = game:GetService("InsertService"):LoadAsset(163348575)
for i,v in pairs(x:GetChildren()) do
v.Parent = game.Players.LocalPlayer.Backpack
end

Appreciate the help.
