I am trying to allow a user in my organization to add the Evenbrite app. The “add” button is greyed out. I selected ‘Manage’. I have added users to the Manage approved users for Eventbrite 2.0. I have chosen **“**Specific users or groups on your account” and entered in the zoom account email addresses that are in my organization. When those users go to the App Marketplace and try to click the Add button, the button is still greyed out. What do I need to do to fix this?
