Normally you do this via search. So the way I'm responding to this is selecting "copy the url to the fediverse" under more and searching for the url on my instance, https://kbin.social/m/kbinMeta/t/201381
. You can see people doing similar here https://lemm.ee/post/1262626 So that seems to work for lemmy/tilvids. Hmm, but that doesn't seem to work for kbin, I seem to get a 500. It's possible the integration isn't quite there yet.
Edit: whoops I responded to a comment deep into this thread, well it's all I could load I guess since I'm getting 500s atm trying to load the mag/this thread
Heads up, the last link in your post has an extra
