When you execute this command you have to specify 5 accounts with their Riot ID and optionally add a lane so that Zoe can start an analysis. Zoe evaluates who could play what on which position (if not already defined) and the champions that could be played (or banned based versus the team) are indicated.
None - every user on a server can use this command (as long as not further restricted by permission)
In this example only 2 out of 5 accounts are specified. In order for the command to work you need to specify 5 accounts.
