Ion-menu - registerAnimation

Hi guys,

Does anybody has experience with registerAnimation within Ion-menu? I try to add new animations to the menu, like the documentation explains here: https://github.com/ionic-team/ionic/tree/3c9ed3166d3a11a4172b5875784c0321311cfd82/core/src/components/menu-controller

I can’t really show any code, because I couldn’t make anything worthwhile yet.
Any example would be helpful.
