installed, but queries go to fallback search

[AvonGee]

I tried ZotHero 2.2 today. The installation seemed successful, and when I type "zot" into Alfred I see some ZotHero Alfred results appear. But when I add anything as a query, like "zot smith" or for that matter "zot s", Alfred just goes to my fallback search option. (This is Alfred 5.1.4, Zotero 6.0.3.)

Is there a set-up step that I'm missing?
