Since mastodon has no equivalent to lemmy’s communities, it can’t handle lemmy’s !community@instance links.
Communities are represented as a regular user on the mastodon side, if you mention a user (using @) on mastodon, it will be parsed as a markdown link on lemmy: [@lucy_idk](https://mastodon.world/@lucy_idk)
