Test fetching current_user

[Flix6x]

In #1358, inspect the current_user object from the WS request and report your findings on this card.

Can you be a bit more specific about which current_user you are referring to?

I found a similar question asked online:

https://www.reddit.com/r/flask/comments/o35xqv/using_flasksocketio_with_flasklogin/?rdt=46422

Although I think we're using Flask-Sock instead of Flask-SocketIO (I haven't investigated the difference, but I think I spotted both packages are from the same author).

Does that help?

Let's discuss tomorrow as a post-demo question whether we were actually right in thinking we'd need this.

We don't think we need the WS endpoint to be aware of the Flask current_user.
