Addons are ONLY working on the pc. Xbox and ps4 cobsolres are not supported.
The video shows how to use minion, download and update addons. I'm not sure what the problem with Minion is for you now?
Is Minion asking for the game to add (Eso, Wow,...)?
Did you add eso?
Was Minion scanning for the addons already installed afterwards?
Did you use the "find more" tab to search for your map addon?
Did you find it?
Did you press the install button?
Did this work (addon is shown at the left tab "Installedc now? Here you are able to update it as it gets updated via the" Update" button (or "Update all" to update all your installed addons).
If this description is not a gelp I personally cannot help any further sorry
