– KaTex support in Rocket Chat

I feel almost stupid to ask this, but how does one enable KaTeX support in Rocket.Chat? I’m using this application in a constructive way to share some math expressions for study with my friends. What I tried so far:

  1. Going through all of the settings in Rocket.Chat. I couldn’t find anything KaTeX specific here.
  2. Went to and tried copy-pasting the scripts in the Install section, under <head></head> in Google chrome developer toolbox.

But, KaTeX simply does not render. Any help or inputs will be super-helpful. I am kind of lost.
