How to send user specific data on Group().send() on Channels?

In my application, I need run a piece of code (let's call it prepare_and_send_data(user)) for every online user, every N minutes. That piece of code will do a calculation using the data that belongs to the user, and send the results over a WebSocket connection.

Initially, I thought that Group('online-users').send({'data': 'data'}) sends the data to the websocket.send channel. Hence, I thought that if I write a consumer for the websocket.send channel, I can do my user specific calculations in the consumer for the websocket.send channel. Hence, calling Group('online-users').send({'data': 'data'}) every N minutes would have been enough to get the application going. Explaining with code:

@channel_session_user_from_http
def websocket_connect(message):
    Group('online-users').add(message.reply_channel)

@channel_session_user
def websocket_disconnect(message):
    Group('online-users').discard(message.reply_channel)

@channel_session_user
def websocket_send(message):
    # Do calculations here, using message.user and send it.

# Call Group('online-users').send({'data': 'data'}) every N minutes, which (I thought) will send the data to websocket.send # channel, hence the consumer for websocket.send channel will handle preparing the user specific data accordingly.

However, Group('online-users').send({'data': 'data'}) does not send the data to websocket.send channel. It sends the data directly over the WebSocket.

How should I handle this? It is possible to use a handler for Group('online-users').send({'data': 'data'})? AFAICT, using a Group to hold the online users is the best option, per the documentation. For this reason, I did not consider alternatives such as holding the online users in a database table. Should I use something other than a Group?

Also, if websocket.send channel is not used on Group('online-users').send({'data': 'data'}), then when is this channel used?

Thanks in advance

Regards
