You should be able to connect to Lemmy communities (Lemmy terminology for subreddits) from kbin by linking in this way:
https://kbin.social/m/{community_name}@{lemmy_instance}
So for example the lemmyworld community from https://lemmy.world has a native link of:
https://lemmy.world/c/lemmyworld
But you can access a kbin.social federated view of it using:
https://kbin.social/m/lemmyworld@lemmyworld
Likewise https://beehaw.org/c/technology would become https://kbin.social/m/[email protected].
You can browse through a big list of lemmy communities here:
https://browse.feddit.de/
I'm not sure how to view kbin magazines from lemmy though.
