Original prompt

Hello, i used to maintain this project however stopped at the time of the recommended versions (readme).

Can you make a new branch called "unofficial" and attempt to update this repository to work entirely on the newest version of spicetify and spotify, please access all relevant information ON github to complete this. spicetify has docs but they may be outdated so put weight on the cli implementations codespace to figure out how things should work.

Classmap should help, history of classmaps, etc. whatever you need.
this is a shot in the dark to see if you can continue to maintain an unnoficial version for latest spotify and spicetify.
