App pairing, is it just for foldables?

[dohouch]

Came across article on how to use it, but on my Pixel 9 Pro, I can get 2 apps on the screen in split-screen mode, but can't make a permanent pair with a desktop shortcut, which is how it should work according to the article I read.
Thanks
PS Now I should go back and find original article.
