*Note* : This is for Shared calendars only, not Group calendars

2)Click on the calendar icon 
3)On the top left, click settings 
4) Click on the calendar icon 
5)Choose “Add shared calendars”
6)From there, type the name of the calendar you require and click the + sign to add

I get a message saying it "cannot add group calendars at this time"
Hi Wade,
Unfortunately, there is a platform limitation, therefore, this will only work for Shared calendars. Thank you for the feedback and I will definitely update the instructions!
