Ring alarm integration: zero devices, so how do I arm from HA?

I just added a Ring alarm to my home and am utilizing the retrofit kit to take advantage of all of my hardwired door and window sensors. All working great. But (aside from the keypad and base station), I have zero Ring “devices” in my system (no cameras, no contact sensors, etc).

I added the Ring integration to my HA instance, and do not see any devices. Is there something no the Ring account side I need to configure to permit HA to obtain device data? It’s unclear to me how I arm my Ring alarm within HA if I do not see any devices with which to interact.
