There are 2 levels that make up the Conferences i/o product -- The Event and the Sessions within an event.
For Events With Only One Session
Not all events have multiple sessions and many of our customers use the product this way.
If your Event only has one Session, your attendees will automatically get brought into that session when they navigate to your dedicated URL.
In other words, your attendees won't be require to click on the session within a schedule.
