How do I hide the furigana in a text box that I can reveal if necessary?

I'm trying to learn through Genki alongside TokiniAndy's Genki course and N5 Anki deck. How do I hide the furigana? My eyes are automatically darting and reading the furigana without my conscious concent (I've tried ignoring. It doesn't work. It's an automatic reflex for me.)

I've seen other decks that have the furigana hidden, except I know nothing about coding. This code stuff may as well be N1 level Japanese.

Does anyone have a copy and paste code to put in the existing code to hide the furigana?
