HatangChatLauncher class
A floating chat button with an unread badge. Place it in a Stack above
your content (or use it as a Scaffold.floatingActionButton with
alignment: null). Tapping calls onPressed, or HatangChat.open.
The button uses the site colour, the icon or image and label set for the
site's launcher in the dashboard (a label makes it an extended button such
as "Hỗ trợ"), and hides itself when the site asks to be hidden while the
team is away (hide_when_offline).
