share Power BI report with SharePoint group

Hello all, SharePoint newbie here. 

I have a series of Power BI reports which are embedded in a SharePoint hero and, at the moment, I grant report viewing access via the Power BI workspace.  

I would instead like to grant access to said reports using the People and Groups already defined in the SharePoint site.  When I go to the permissions section, I can see the groups for Read, Full Control and View Only, but I don't know to translate those into groups which Power BI would recognise. 

Is this possible? 

How do I do it?
