Check the box to Enable read-only calendars in case you want to be able to view shared calendars in which you do not have full access to.
Step 4: Select Calendars to Sync
Select the Calendars you want to include in Bi-Directional Sync.
Step 5: Finished!
Your Sync’d calendars will show up with the Titles and location “GOOGLE: CALENDARNAME” and your all done, your calendars will now be synced with Google Calendar.
