To improve a function

Hello,

I am still an Elixir newbie. To learn I keep on asking questions like this…
Can I improve this two functions? It feels like but I do not know how.

  defp get_url(team_id) when team_id > 0 do
    "a_url_removed_because_not_public" <>
      Kernel.inspect(team_id)
  end

  defp get_url(team_id) when team_id == 0 do
    "a_url_removed_because_not_public" 
  end

besides doing them as one-liners:

  defp get_url(team_id) when team_id > 0; do:  "a_url_removed_because_not_public" <> Kernel.inspect(team_id)

  defp get_url(team_id) when team_id == 0; do:  "a_url_removed_because_not_public" 
 

It still looks as it contains too much redundant code.
