Broadcast message for current_user from external non rails app

I have ActionCable channel that identified_by current_user.

class DesktopNotificationsChannel < ApplicationCable::Channel

  def subscribed
    reject and return unless current_user.present?
    logger.add_tags 'ActionCable DesktopNotificationsChannel', current_user.id
    stream_for current_user
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end
end

And i can subscribe this channel from my dotnet desktop application without any issue with subscribing like this

But when i want to broadcast message from my dotnet app im sending json below with proper encoding

{
    "command": "message",
    "data": {"status": "current_status"},
    "identifier": { "channel": "DesktopNotificationsChannel"}
}

When i debug action message_buffer successfully got message but then nothing happens. I figured that i have to add user id or g_id to message but i couldn’t succeed it, I tried to send channel_parameter like desktop_notification:g_id etc but result didn’t change.

What am i missing?

I managed to fetch messages by adding stream_from and receive method to my channel. I don’t know its proper way to do but it but it’s working like this.

class DesktopNotificationsChannel < ApplicationCable::Channel

  def subscribed
    reject and return unless current_user.present?
    logger.add_tags 'ActionCable DesktopNotificationsChannel', current_user.id
    stream_for current_user
    stream_from current_user
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end

  def receive(data)
    DesktopNotificationsChannel.broadcast_to(current_user, data:)
  end
end
