Hey, I've been getting used to my Chrome plugin Stylish to add dark mode to different websites that I frequent. Now I'm trying out Franz, and I quite like it - but I am missing the dark modes. I saw in documentation for recipes, that adding dark mode option is as simple as adding a CSS file to the recipe.

I've been using the following in Stylish:
https://userstyles.org/styles/136318/clear-dark-facebook-by-book777

It also styles messenger. Could you add this css to dark mode for messenger?
You can click button "Show CSS Code".

There's also a "Customize Settings" button, but I'm not sure if the CSS shown on the page changes directly. But personally, I prefer the Dark gray-black or Darker gray-black themes.
