Zwave2MQTT/Supervisor Add-ons filepath?

To assist with an add-on (ZwaveJS2MQTT/ZwaveJS) bug issue, I’ve been asked to modify a file within an add-on that runs in supervisor which runs on a HassOS server.

Using SSH (Terminal & SSH loaded) into my server, I have not been able to locate the filepath to ZwaveJS2MQTT. Did file and filepath searches with my FTP client and I’m having no luck.

Any suggestions, places to look, things I need to do to find this folder?
