How to open a post link from an instance into another instance?

Hello, Lets say that I found a post on lemmy.eus, for example: https://lemmy.eus/post/168138 I want to comment on it, but I don't want to create an account on lemmy.eus as I already have one on lemmy.ml and lemmy.world. How can I find easily the post on lemmy.world so I can comment from there? I tried to use change eus to world in the url but this does not work.
