Is it possible to have a channel for a websocket created using cowboy2.

I have two sockets in my application. One of the websocket is using cowboy2. I am not able to create the channel for the websocket.
My websocket endpoint is /ws/feeds

I have this in my sys.config

{"/ws", 
        'Elixir.Phoenix.Endpoint.Cowboy2Handler',
        {'Elixir.Phoenix.Transports.WebSocket',
        {'Elixir.OctopusWeb.Endpoint',
        'Elixir.OctopusWeb.FeedsSocket',websocket}}},

Endpoint.ex

  socket "/ws", OctopusWeb.FeedsSocket,
    websocket: false,
    longpoll: false

FeedsSocket

defmodule OctopusWeb.FeedsSocket do
  use Phoenix.Socket

  require Logger

  channel "feeds_channel", OctopusWeb.FeedsChannel

  transport(
    :websocket,
    Phoenix.Transports.WebSocket,
    serializer: [{HydraWeb.Web.Transports.BinarySerializer, "~> 1.0.0"}]
  )


  def connect(_params, socket) do
    Logger.debug("feeds socket connected")
    {:ok, socket}
  end

  def id(_socket), do: nil
end

Feedschannel.ex

defmodule OctopusWeb.FeedsChannel do
  use Phoenix.Channel

  require Logger

  def join("feeds_channel", req, socket) do
    Logger.debug("feeds channel connected")

    {:ok, socket}
  end
end

Please help me where I went wrong.

Change websocket to true.

If I change websocket to true. The route will be /ws/websocket
I need the route as /ws
