Above is a snippet of config.toml in my forked repo
I want to use mmt icon for YouTube, YouTube Extended, YTMusic, YTMusic Extended and the default display name in the app drawer is YouTube and YTMusic
But after building the modules and installing in kernelSU, the icon set is revancify_blue instead of mmt, the app name is YouTube ReVanced, YouTube Music, RVX Music
Furthermore, with Reddit Extended I want to name the app Reddit RVX but in the old version of your repo you can do these things via options.json, which now only uses config.toml but there is no corresponding conversion option
For example, below is the old options.json that meets my wishes
