Ability for user to close the chat widget

There are already 2 methods to close the chat window: awesomescreenshot.com/image/50...

Is this what you meant?

Great idea, Also sometimes clients are complaining about not being able to close the chat, a small X in the corner of the chat design could be really helpful

If this is to close that chat bubble that is placed on the very right bottom of the webpage. Don't you just click it again in order to close it or click on the "X" at the top right of that small window that has been lanched in order to comunicate with the chatbot? I think this is something that the user should know. But hey maybe I'm talking about something totaly different. Sorry....
