How do I add an external converter file in zigbee2mqtt LXC?

[vdiogo]

I want to add a Zigbee device which is not supported by z2m, so would like to add the .js file in z2m config folder.
How do I achieve this please?

Thanks, I did saw that prior raising this Q, but my question is, considering z2m is installed in a container, how do I get an external file to be put on the same folder as the config.yaml?

I'm not familiar with Linux and such, so any guidance would be welcomed

The instructions on the website shows the path to the configuration.yaml

I read save it next to the Zigbee2MQTT configuration.yaml but how to I get access to it considering it's installed on a container?
I have the .js file to be used as external converter, but how do I put it there?
I also understand I can reference a url from where the .js file can be fetched - trigger OTA update - but after multiple browsing on the internet, I can't find my way around it on how to list the folder, access it, and eventually edit the config.yaml to reference OTA alternative url

I'd suggest installing File Browser in the container as a way to have a graphical user interface (GUI) for uploading, downloading, and editing files.

Awesome, great guidance!!
Did it (and of course used your script) :)
