I used the Trello macro to embed a board in one of our Confluence pages, and this article here says I should be able to do anything in this embedded Trello board that I can do on the Trello site. However, I am unable to add cards.
Also, how do I limit who can change/edit cards? I would like only the board admin to be able to do that, even though anyone should be able to add one or change their own.
