Change font size via ~/.config/neochatrc

Howdy. I’ve read in a previous thread that there is currently no way to change the font size in NeoChat from the GUI. However, I’ve tried to add font settings to the [General] block of the neochatrc block in my home .config directory and nothing seems to take. Is this intentional? Apologies if I’m missing something, new to KDE apps in general. Thanks!
