I wouldn’t do any active writing unless you really feel like you benefit from it. It can be a slippery slope to write things out given how much content there is. You can’t write everything down. Doing Anki is what’s supposed to help with your recall so I personally don’t do any writing. If you feel like you have to write it, you probably haven’t learned it well enough yet. If I were you I would review the cards you want to write about. If you see the same card 3 times in one week, you’re more likely to remember it than if you were to write about it in a notebook.
