Hi,
Thanks so much for reaching out and for your interest in our products!
In order to import Facebook Events, you can use our Event Aggregator plugin. Once configured, you will see more options appear in your Import Settings, where you will be able to connect Facebook to Event Aggregator. You can choose a one-time import, or automatic scheduled imports. You can also enter the URL of your events page as well.
Here is what it looks like:

I hope this helps to answer your questions, please let me know if anything else comes up!
Thanks,
Jaime
