Missing abode security system in Home app guest access

In the security section of my home app, I have a garage door opener, a deadbolt, and an abode security system. When I try to create guest access, the only options are to toggle on or off the garage door opener and the deadbolt, but the security system does not appear. Any ideas how to fix this?
