Schlage Encode lock

How do I add this lock (Schlage BE489WB) to my IQ 4 panel?

From alarm.com app not from panel. But my add devices like lock and others are missing on my alarm.com app. Thet were there earlier

Schlage Encode is a wifi device added via Alarm.com. It is not added directly to the panel.

Visit Settings > Manage Devices > Add Device within Alarm.com.
