About music cover

Hello! Is there any tutorial about how to use the cover art codes($mi(cover)$)? I'm struggling to get it working. Any help is appreciated!

Put an image in your preset, in the choose image option tap in the checkbox in the right of the word, tap in the calculator in the top of the editor and tap in the new calculator in the choose image option to open the code editor, put the $mi(cover)$ code, tap in the tick in the top right of the editor to save the code, done. This work with almost every music player, but maybe you can have problems with some that not broadcast this information. You can choose in the Kustom app in settings if you want automatic or one of the players that you have in your phone.

works perfectly! thank you so much!
