Where can I change the Expert(RApp) font?!
Modified the config file in the theme folder.
The name's gone but

So I want to change the font to AdobeBlank.ttf, but I don't know what to touch
theme - config

{
    "name": "Neumorphism-Black",
    "author": "bantam",
    "batteryPercentage": {
        "visible": true,
        "font": "/mnt/SDCARD/miyoo/app/omyu pretty.ttf",

        "color": "#E1E3F1",
        "offsetX": 0,
        "offsetY": 1,
        "onleft": true
    },
    "title": {
        "font": "/mnt/SDCARD/miyoo/app/omyu pretty.ttf",
        "size": 35,
        "color": "#E1E3F1"
    },
    "hint": {

I'm not sure which font is used, trial and error is the way.
