Can't add to HA zigbee2mqtt after successful Flash

I'm hoping to be able to make this work:

I need help adding two flashed devices to my Hame Assitant Zigbee2MQTT addon.

I successfully flashed two "Mi temperature and humidity monitor 2" with this:
https://github.com/atc1441/ATC_MiThermometer/releases/tag/79
Starting up it shows "Atc", and I can control both with the "Telink Flasher for Mi Thermostat" page on my mobile.

I've update the HAOS configuration.yaml file with the external_converters:

homeassistant: true
external_converters:
  - lywsd03mmc.js
advanced:
  network_key:
    - 151
...

and created lywsd03mmc.js in the zigbee2mqtt folder, and copied the new version from converters/lywsd03mmc.js in this repo.

My Home Assistant Add On says: Zigbee2MQTT Current version: 1.36.1-1.

On the a2mqtt UI I "Permit Join", but the devices do not appear. I tried restarting by removing the battery and waiting a few seconds, as well as resetting by linking the the Gnd and Reset connectors. Nothing appears to try to connect. There is nothing related in the z2mqtt logs either.

Am I missing a step? Is there anything I can do to debug this?

Holding the gnd and reset for around 10 seconds made the connection for me on two thermometers. Fresh Z2M install, without any additional .js files.

I was able to solve it!

I relied on too many sources, but it worked when I followed the instructions here.
An important note:
I used Chrome on both my PC and mobile. I could connect one sensor only to my PC and the other to my mobile. This is very confusing and takes some time to figure out. If others had a similar experience, it's worth mentioning in the doc.
