Any modules to theme my SystemUI?

I recently tried to make my own RRO (Runtime Resource Overlay) theme that changes my navigation bar icons to One UI's, but it didn't work. I also tried to go online and tested a module too, but it still doesn't work. The module in question is: https://github.com/jairaj08/SystemUI-Patcher

I also heard that SystemUI on Android 15 and later have changed so that module won't work. Unfortunately, my LineageOS version is 22 and it is running on a Motorola edge (2021) codenammed berlna, which is based on Android 15.
Any suggestions on how to make it work?
