Hello,

Unfortunately, the floating button appears on all YouTube pages and even these pages :
- https://www.youtube.com/account
- https://www.youtube.com/feed/history

Sometimes 2 floating buttons appear on the watch video page :-(

Thank you for your answer.

I think you need to replace lines
// @match https://www.youtube.com/*

with something like this
// @match https://www.youtube.com/c/*
// @match https://www.youtube.com/@*
// @match https://www.youtube.com/user/*
