I want to copy a Notion Workspace or parts of it before I am going to lose
access to it. I can log into Notion and view the workspace but can't get
HTTrack to download it. I am not sure what I am doing wrong or if that is not
possible at all. 

I tried the method described in the FAQ to use user:password@your_url
(example: <http://foo:bar@www.someweb.com/private/mybox.html>)
but that did not work. 

Can somebody help me, please?
