Managers can add curators to studios by navigating to the "Curators" tab, typing the username of the user they wish to invite and pressing the button that says "Invite". An error message will appear if that user has already been invited or they are already a curator of the studio. The user will receive a notification inviting them to curate the studio, in which they can choose to curate the studio or ignore the invitation. It is not currently possible to decline studio invitations.
