how to embed this with youtube, or as an extension to work with youtube

[FaourA]

i'm working on using this tool to embed it into youtube, through revanced as an api or in anyway, or as an extension, or as an apk or seperate app, , i'm not sure. i'm learning, does anyone know how i could do anything like that, main goal being: you click on a youtube video, it may process for a few seconds, then it plays only vocal, no instruments. i hope you can advise me on how i could do this or how i could learn how to go about doing this, and which bots to use so it can be time efficient, yet high quality removal of instrumental, thanks
