show Simpul events calendar as calendar

I am new to WordPress so this may be a very basic question but it has me stumped.
I would like to show our event’s calendar as a calendar rather than a list of events. Simpul events says that it has this capability. I dragged it into the Main Sidebar and selected the options to show the calendar. I hit save and yet on the webpage, I only see the original “events calender” with the events in a list. What am I missing?
Thank you!
