Set availability_topic for device added by UI configurator

Hi, I have MQTT integration added via UI. Because of that, I don’t have device entry in my configuration.yaml file. Now I want to configure availability_topic attribute for one of my zigbee device and I don’t know how to do this. Should I remove MQTT integration and add it via configuration.yaml file? Or maybe there is a way to add custom attribute using UI. My HA is running inside container.

Here is an example, how this looks like for entries added in yaml file: Detect online/offline state of ikea zigbee bulb - #33 by thmry
