In case of "Project Roles" you just need to tick those that you wish to give an access with. For "Groups" and "Users" use a relevant "Add" button.
After adding such, they will be able to access "Scheduled Issue Wizard" and manage it with full rights (i.e. edit or delete somebody else scheduled issues, or create scheduled issues in someone else's name).
