Flashing BK device?

Hi

I used tuya cloud cutter on an Arlec power socket, all went in OK and can now connect to its ip and it has a web interface for me to upload firmware to

I created a new device in ESPHome

esphome:
  name: arlec-2ch-usb01
  friendly_name: arlec_2ch_usb01

bk72xx:
  board: generic-bk7231n-qfn32-tuya

however, i cant flash it, i get this

BK devices do not use an ESP chip, but a Beken chip, which is not compatible with ESPHome.

Edit: Well, maybe you can. https://www.youtube.com/watch?v=t0o8nMbqOSA

The mentioned bk7231n is compatible with esphome according the docs.
