I have homepage installed through TrueNAS as an app which works and allows me to access the web portal. However the config files are stored in 'ixVolume' automatically, and I'm not sure how to access them to modify homepage. All the tutorials I have watched on YouTube install it through the command line on Ubuntu or other Linux distros.

This might be a dumb question since I'm new to selfhosting but thanks for any advice.
