How do I subscribe to a community that exists but is not showing in search?

This is probably a dumb question, but I'm still figuring this all out. How do I subscribe to a small community that I found in the community browser but cannot get in search?

Eg: https://midwest.social/c/lansing

It exists but does not show in any community search via sh.itjust.works website, liftoff, or sync. I can view the community from the browser but trying to open it just takes me to their instance. !lansing@midwest.social doesn't appear in search either.
