We see very nice demos at the Alteryx Academy. Trainers showing some actions, tips and tricks on screens previously recorded...
Originally you need to install a software like;
Then learn how to use them and share separate video or moving GIF files with people manually by mail etc....
I suggest a screen recorder for Alteryx where you can quickly record and save how something is done
and then share it thru Peer to peer with a colleague one-on-one or publish to the Alteryx Community...
It may even be an awesome thing if one can share screen in real-time with another Alteryx user...
Then it will be top notch collaboration...
