Frontend confusion

I installed pleroma-fe, akkoma-fe, mastodon-fe and fedibird-fe.
But when I set e.g. Primary to fedibird-fe / ref akkoma, I get the “no frontend installed” message and besides that, /var/lib/akkoma/static/frontends/fedibird-fe/akkoma contains no index.html. What am I missing?

it’s a mastodon fork, so I assume you can’t set it as primary. You need to set it as the mastodon fe.
