From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I was using fork of this extension. Original one you've mentioned works in Kate too, thanks! I hope I will not return to this question anymore. I think this one has a bad name, it's easy to overlook it in search through gnome extensions website.
I use copyq on wayland everyday. But not gnome, on hyprland.
Cliphist sounds like it might work for you. Depending on what's running under Gnome you might need a few dependencies.
