That very specific facility was covered a couple of weeks back in the Fediverse City matrix room. I can't remember the URL or specific name (Kinda like the old "Add to Any" plugin for Drupal and WordPress), but just scroll back a bit as there was some discussion over it.
I do remember that it was kinda disregarded because it didn't work on most Fediverse platforms - only mastodon when tested, IIRC, so its worth is minimal.
