 Review comment:
   Does this support refreshing individual workbook report or the whole workbook ?
   Say I have:
   `https://url/#/site/site_name/views/Calls/Department`
   `https://url/#/site/site_name/views/Calls/Agents`
   if I pass `Calls` would it refresh both `Department` & `Agents` ?
   What if I pass `Calls/Agents` ?
