I don't think this is possible
Should be. I know the URLs don't match up, but you can do a search for (what Connect shows as) "Lemmy link" from another instance.
So you would;
- Get the "Lemmy link" from the opened post (this is the URL of the original post)
- Switch to the other user
- Do a search/lookup for that URL
- Display it
I was trying this manually from Connect, but it looks like searching for a URL doesn't work through the search interface there, so I can't test it. Should work though, as those searches are OK through the web interface.
The URLs Don't match, not even the post id's are the same. This would be a big point of failure. Especially when its on different instances. The steps you made have the key issue in step 3, thats not possible.
It is possible.
Search for the "Lemmy link" URL. Works on the web interface, no reason why it won't work through the API too: (it's the same theory as doing community lookups)
