What permissions are required for a SWSD user to view dashboards?

Greetings SWSD Users,

Our management team is asking to configure SWSD so that IT liasons from different departments can view a dashboard that pertains to that department's ticket status, etc.  Is that possible, and if so, what permissions are required for that?  We created a custom role called "Dashboard Users", but have yet to determine what permissions accomplish what is needed to achieve our goal.

Thank you for taking some of your valuable time to respond and/or read this question!
