Sure! I only need the name - here is what I have in the Notification Email Script:

var emailBody = onCallSchedule();

       template.print(emailBody);

   

       function onCallSchedule(){

               var groups = [];

               var gr = new GlideRecord('sys_user_group');

               gr.addQuery('JOINsys_user_group.sys_id=cmn_rota.group!active', '=', 'true');

               gr.addOrderBy('name');

               gr.query();

               while (gr.next()) {

                       groups.push(gr.sys_id.toString());

               }

       

               var fsr = new FormattedScheduleReport();

               fsr.buildSchedule(groups.join(','), gs.today());

               var html = fsr.getReport();

               return html;

       }

And my output is when in Notifications:
