Multiple game modules - Documentation page

I just want to ask, if that page is still up to date ? Especially the DefaultEngine.ini steps. I honestly forgot to do it, and my additonal module still worked. But then I read it again, and added it to my config file. But it didn’t make any difference. So I guess these steps are obsolete ?

I would like to know too.
How did you manage to get your module to work? I’ve followed this Gameplay Modules in Unreal Engine | Unreal Engine 5.3 Documentation and I can’t make it work.
