cannot add external nerd font

[melsiir]

in my machine i can install font to use it i must just put it in certain folder for my terminal and my terminal will recognize it but Its not really installed and there for I cannot use it with silicon nor it appears when running silicon --fonts-list.
So it think it will be better if I can just add it to silicon like this
silicon app.js --font ~/fonts/jetbrains.ttf
