Hi,
I can help answer your question. The Events Calendar generates rss feeds that people can subscribe to and get updates when new events are created. They can use the buttons for iCal and Google Calendar to manually get information about events. I can see that as a potential feature in the future, if you think that is something you would like as a feature I encourage you to visit our User Voice Page and either upvote an existing request or make a new request there.

Let me know if you have any follow up questions.
Thanks
