Can't find the config folder for zwave with Innovelli

I’m using the VirtualBox installation of HA on a Windows host.

I’ve read the instructions to integrate Innoveli with HA however I can’t find the config folder: https://support.inovelli.com/portal/en/kb/articles/installation-setup-lzw60-4-1-multi-sensor-home-assistant

Also, I’m a little bit confused about how to access terminal in the proper way. Currently I’m using the built-in terminal from Visual Studio Code. Also, how do you transfer files to HA when you know the config folder? Through Samba?
