How to yank text from a kill-ing and instert it at the cursor location in another terminal window?

How to copy, if it is possible at all, a text from one terminal and paste/input it into another without selecting it?

More precisely, within the same terminal window, I can kill the text line by CTRL-U and then yank the killed line by CTRL-Y. However, CTRL-Y doesn’t seem to work when trying within another terminal window or even to another terminal tab.

I’m using bash 5.1.16, Konosle terminal in a KDE desktop environment (plasma 5.27.6) in Arch Linux x86_64.
