If I am looking at a post on another instance, how do I best find the corresponding post on beehaw?

For example if I am on https://lemmy.ml/post/1181103 how do I most efficiently open it in beehaw so I can interact? There is a sidebar that says

You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !fediverse@CubitOom@lemmy.ml

I have not been able to follow these instructions successfully. idk about anyone else.

I can eventually find my way to the beehaw post by manually adding the name of the group fediverse@lemmy.ml to make the URL https://beehaw.org/c/fediverse@lemmy.ml and searching in the page. Which is really not very smooth.

But what if I was looking for something that was not one of the most recently posted items? Do I just have to manually scroll?

Is there any corresponding identifier of the post that is consistent between instances? There must be, right? How else could they all interact otherwise.

Any help would be welcome as I am constantly ending up on other sites and this is very cumbersome.
