Yeelight mi bedside lamp 2 firmware

Hi,
I have two questions:

  1. Does anyone have a firmware of “mi bedside lamp 2” to download it ?
  2. I am trying to understand what is “Yeelight 3rd-party control protocol”, how does it work ? if i click on enable LAN Control via the the app, what happens behind the scene

It allows you to control the lamp from your LAN via json commands and allows 3rd party applications to control it (from your LAN)
