I added a user to my board but he/she cannot use the Power-up

Each user must authorize the Power-Up by clicking on the Power-Up name on top of the Trello UI and going through the auth flow.

Any person who wants to use this power-up must be a member of the Trello workspace where the board exists. It's not enough to add a user to your Trello board, you need to add that person to your workspace as well.
