Dark page toggle in context menu

In opera, you have the ability to toggle dark mode on-the-fly with the context menu. I prefer brave much more than opera and would love to see this implemented. I understand there are extensions for this, but they tend to load pages slower and sometimes need toggled off and on again to even see text on some articles. I am also aware that you can enable this in flags, but that requires a browser restart every time it’s enabled/disabled, which obviously isn’t ideal. Some websites it is borderline unusable on, so an on-the-fly toggle like opera has would be absolutely amazing! And having it remember what websites you toggle it on/off on (like opera does) would also be great. I’m including a screenshot to display what I’m talking about. Thanks!
