How to change "docker run" command for zigbee2mqtt docker?

Hello
I want to add new device to zigbee2mqtt using information from here:

I have done almost everything but I have stucked on docker section.
Almost all has been done and finally I have to change “docker run” command option to:

Now add the volumes to the Docker container by adding the following to your `docker run` command.:
-v /opt/zigbee-herdsman-converters:/app/node_modules/zigbee-herdsman-converters -v /opt/homeassistant.js:/app/lib/extension/homeassistant.js

Where can I find “docker run” script for zigbee2mqtt to change its parameters?

Same place as you ran it the first time you ran zigbee2mqtt in docker.

I run it from Home Assistant. So just click Start from Supervisor->Zigbee2mqtt on Home Assistant web gui.

Ok so you are using the addon, then I am not sure.

Does this cover it? https://github.com/danielwelch/hassio-zigbee2mqtt#using-external_converters

Otherwise, post an issue on that github.

Yes, I am using that addon.

So, it seems that I should use shephered mode?

zigbee_shepherd_devices: true

and now I have in configuration:

data_path: /share/zigbee2mqtt

Is this path to directory on my ubuntu or in docker where zigbee2mqtt is installed?
