Does Steamworks API work with HTML5? UE4

I tried packaging Steamworks API into my game but got the following errors. Any light? The game compiles correctly up until the linking. Is this even possible? How would steam handle a HTML5 game? Compiles correctly with Win64.

[2/2] Link [GameName].js

is the plugin enabled for HTML5? it might need to be whitelisted in the *.uplugin file. and it might also need to be set/configured in the *.Build.cs file for HTML5 as well.

Any answer to this? I have the same issue with different platforms
