1st: Wrong forum as Minion got it's own forum
2nd: Please read this as your topic exactly is described and handled there. That's why the posts are "sticky" at the top of the help forums
-> Especially below "Why can't I see any addons inside the game's AddOn manager?"
Hint1: ESO stores the addons in your users/.../documents folder. OneDrive and ESO do not work together so disable OneDrive or in the OneDrive setitngs disable the dync of your "documents" folder.
Hint2: Minion should use the users/.../documents/elder scrolls online/live folder as explained in the sticky post.
Use the ingaem screenshot method to see the folder name in detail, ingame.
