Testing sockets in phoenix

I am totally new to sockets and its my first time using them. I have very simple config. In endpoint I have simple default user socket.

          socket "/socket", ApiWeb.UserSocket,
            websocket: true,
             longpoll: false

In user socket I have the following code:

      def connect(%{"token" => token}, socket, _connect_info) do
        case Nuton.Guardian.resource_from_token(token) do
         {:ok, user, _claims} ->
           {:ok, assign(socket, :current_user, user)}

         {:error, _reason} ->
        :error
       end
      end


      def id(socket),
                        do:
                           "#{socket.assigns.current_user.phone_number || socket.assigns.current_user.email}:#{
                               socket.assigns.current_user.id
                             }"

When I try to test it with any online websocket client with the following url:

           ws://localhost:4000/socket

It won’t work and In the console I will get error message that
no route found for GET /socket

. I don’t understand why it’s hitting the router and not the socket. Is there anything else I need to do.
Thanks

What happens if you try
ws://localhost:4000/socket/websocket
