Once you manage to go through login (apologies for non staff limitation) and after selecting ENROLL ME you are faced with helpful stuff for Moodle use. Like in the story of Ali Baba and 40 Thieves. This time is not Sesame Open but Moodle Open.
If we can not find on the surface why don't we dive deeper. At least that works for me. I have found some interesting tips in this post. It would be useful if I manage to use this in my Project or at least if I open that notion to students using it later on.
