So I am following a 2-week course from unity for starter, and in here one mission we are supposed to build a game using WebGL builder and WebGL publisher package, now its asks me to check if webGL publisher package is already installed or not and if not then install it.
Now to install it, the WebGL publisher package should be in the unity registry of the package manager, but in my case there is nothing. plz help me

my unity version is 2020.1.6f1, what should i do now
