Try putting the full provided link (as posted, no editing, so: https://lemmy.blahaj.zone/c/lemmy_wishlist) in search bar of your instance. This should prompt this community to start getting federated on your instance and then it should be accessible at https://lemm.ee/c/lemmy_wishlist@lemmy.blahaj.zone
Ok, now I understand. I was previously pasting it into the community dropdown meanu in the lemmy search page, but not in the search bar.
I meant search page I guess. There’s a magnifying glass Icon at the top of the page. You should see something like this on the Image here. And then you can subscribe to the community from your instance
Most importantly - has it worked for you? If so, I’m glad I could help. If not, I’m sorry, but I’m still pretty new to this and don’t know much yet
