Confucianism which advocated moderation

In fact, most of the artworks from the late Joseon Dynasty are simple in appearance, likely due to the influence of Confucianism which advocated moderation.

I feel like there must be a comma between Confucianism and advocated moderation like Confucianism, which advocated moderation or does which there modify others and a comma is not needed there?

What do you native English speakers think? Thank you so much as usual in advance.
