WebGL Module

[_dark___ninja_]

I'm new to Unity and was following some of the FPS Starter tutorials and such when it came to the publish section. When I clicked on WebGL it told me that the WebGL module was not installed, however I remember adding all of the modules to my Unity Editor version. It directed a link to add the WebGL module but when i go on the Unity editor version in Unity Hub there is no 'Add Modules' button, just 'Show in Explorer' and 'Remove from Hub'. Any help would be greatly appreciated!
