Pubnub get all messages of all channels in a group in single stream

In Pubnub channel groups feature , how can I get all the messages of all the channels in the group as mentioned here

"if you subscribe to the Channel Group, you get all messages from all the channels in the group in a single stream"

I couldn't find any API to get all the messages of all the channels of a group in a single API call.

PubNub Channel Groups: Receive vs Fetch Messages

Single stream just means you can subscribe to a channel group which in turn means you are subscribed to all the channels in that channel group (up to 200 channels total). And you can subscribe to 10 total channel groups per client for a total of 20K channels. The single stream which it refers to is the connection to PubNub. One connection (stream), up to 20K total channels.

With PubNub, you don't fetch messages, you receive them in realtime when they are published. But if you truly meant fetch messages that have already been published but the client was not connected at the time, then yes, you need to call history to get old messages.

But the link you provided says nothing about fetching messages. It talks about subscribing to channel groups to receive messages from many different channels (friends' channels, in that design pattern) in realtime, not fetching old messages.
