/chals => 404

I'm trying this on demo.ctfd.io, but this leads to an error. For ctfd.io this URL offers the list of challenges: https://demo.ctfd.io/challenges (or as admin: https://demo.ctfd.io/admin/challenges) Would it be an idea to have a command line argument for this URL?

ctfdfetch -s https://demo.ctfd.io -u xxx -v
