“configure device” button

The update notes for 2021.4.0 state there’s a new page to setup config parameters for z-wave devices. I absolutely cannot seem to find this menu! I have Z-wave JS installed as an integration and an add-on. Everything is working just fine. I’ve looked in the zwave JS configure menu and system options menu. I’ve looked in the ‘device’ page of various zwave devices. I’ve tried the actual z-wave stick’s device page. I’m prepared to feel real silly, but: where is the ‘configure device’ button?

core-2021.4.0
supervisor 2021.03.9
Home Assistant OS 5.13

It is accessible on the Device page.

I had just finished a reboot, and there it is! Thank you kindly.
