Allowing specific roles to view

I have a page using Events Manager. I have a link below the calendar for specific members to use to add an event to the calendar. I have selected the “Logged in” option for viewing the link. Just below that option is a box where you can type in specific user roles to view the link. I have tried several different ways to type in user roles but am not having any luck. I would like to set this up so the Admin, Shop Manager and Editor roles can see the link and no others. But I do not know what to type in the box.
