Show notification for all channels

When this checkbox is checked, a notification badge will be shown to the users and the notification will be sent to all the users in the chatroom for all the channels in the chatroom.

If this checkbox is unchecked, then the notification will be sent for only the channels the user opens.

So, for e.g if you have created 5 channels in the chatroom, and the user doesn't click on the channel name to open the channel in the chat they will not see the unread badge for messages sent in those channels.
