Hello, Guix! It might be this question was somewhere, but I did not found on guix-help archive and duckduckgo.
Please, what to do for LibreOffice Writer make a spell check?
It has no any spell check module now and dictionaries are empty. I've just installed it with `guix install libreoffice`
`guix search libreoffice` does not show any language pack.
My system config attached.
