Active bluetooth proxy for BLE LED lights?

I have a ESP32 board configured as an active bluetooth proxy. I have what I believe is the correct configuration and the logs suggest that it is “seeing” the BLE LED lights. But they are not showing up as “discovered” in the Settings > Integrations screen. Is there somewhere else I should expect to see the lights show up?

ESPHome config:

substitutions:
  name: "esp32-bluetooth-proxy-1"

esphome:
  name: ${name}
  name_add_mac_suffix: false

api:

logger:
  level: DEBUG

esp32:
  board: nodemcu-32s
ota:
  
wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

bluetooth_proxy:
  active: true

Are you sure those LED lights are supported?

Well, these same BLE LED lights HAVE shown up as discovered if I hook them up close enough to my HA RPi4. And I even configured one of them and could control it completely. So, from a HA perspective they are supported.
And looking at the “lights” section of ESPHome it appears they would be supported by ESPHome as well.
But it was my understanding that the ESPHome BT proxy was doing just that, proxying BT packets between the end device and the HA bluetooth integration. No?

Did you hide/ignore the previously detected ones from HA, or did you delete them? Check for hidden ones and unhide them. At least for my xiaomi plant sensors, HA did not see the difference between one connected though a proxy and one connected directly. They are the same one. So maybe it is simply ignored.

Yes, I deleted all ignored BLE LED lights.
