Adding additional languages for spell checking
How do I add additional languages for spell checking in Geary? Currently I can only see different variants of English. Following https://wiki.gnome.org/Apps/Geary/FAQ I installed Apsell and aspell-sv but I can't see Swedish as choice under the "book" in the composer in Geary.
I'm running
Ubuntu 18.04
Geary 0.12.4 (Flatpak)
Aspell from Ubuntu repo, aspell -v @(#) International Ispell Version 3.1.20 (but really Aspell 0.60.7-20110707)
