Considering some people said there is a difference between "attend" and "participate" in Scrum exams, and Scrum Guide only mentions non Scrum Team members can "attend" Sprint Planning, my question is:
Can non Scrum Team members "participate" in Sprint Planning ?
Because recently I read from an example mock test and it said non Scrum Team members can "participate" in Sprint Planning but Scrum Guide doesn't say that and I think they can't.
