If you’re trying to share your calendar with another app, you’ll want to set up a specific key for that in the calendar setup.
Go to the property calendar page, and from the drop down menu select setup calendar sync
Open the basic calendar sync app
under View by Connection, click New Connection
Select the channel you want to connect with or type if calendar sync and complete the export setup.
You’ll receive a unique key to use for the connection.
Hope that helps.
