Dark Mode for Khan Academy

As a person who uses Khan academy a lot, I wish they added a dark theme. Well yes I could use third-party extensions, but I tried them and none of them gave the results properly, for example, I used this chrome add on called invert and it did do a good job, but all the videos I watched also had its colors inverted and put a lot of stress on my eyes.
