Font for the file folder tree

I’m trying to increase the font size for the text in the folder tree (left panel). I know how to increase font for the reading pane, that’s easy. Can anyone tell me if its possible to change the font of the note names (some people might call it a file name).


Things I have tried

You could try this snippet to start. It changes both the folder and note name sizes.

body {
    --nav-item-size: 16px;

// moved to custom CSS
