How do I subscribe to a community on another Lemmy instance?

How can I subscribe to a community on another Lemmy instance using the Beehaw account? I feel a bit embarrassed asking this question because it seems like a basic task, and I may have overlooked something obvious. However, I did make an effort to search the internet before coming here.

Here are the steps I've tried, which don't seem to be working:

1. On Beehaw, I navigated to the "Communities" section.

2. In the search bar, I attempted several searches:

   • https://programming.dev/c/meta

     => Result: The search page appears empty, without explicitly stating "No results." However, I can click the "next" button an infinite number of times.

   • I tried entering [email protected]

     => Result: It displays "No results."
