[Mailman-Developers] Hyperkitty 1.0.3 doesn't have add_user_to_mailman function

Latest mailman-bundle, Hyperkitty==1.0.3, python-social-auth==0.2.21.

https://gitlab.com/mailman/mailman-bundler/blob/master/mailman_web/productio... https://gitlab.com/mailman/hyperkitty/blob/master/hyperkitty/lib/mailman.py

Im trying to implement a custom authentication backend by following a tutorial. In the tutorial, the version of hyperkitty is actually 1.0.4, and the whole thing works well. However, it didn't work on top of 1.0.3. I can find this function in commit 1755122c https://gitlab.com/mailman/hyperkitty/commit/1755122c708abc96933142ca77dd0ff...
