Google chrome jetbrains plugin

I tried following the kotlin tutorial for intelij (except that I’m using gradle for the configuration).
When I right-click index.html, I don’t see the “Debug” option however
I can open it with Google Chrome (again from the right-click menu).
I have installed the jetbrains plugin on google chrome but it doesn’t
show as connected but I can connect on localhost:63342 from the
browser.
Here’s a screenshot

JavaScript debugging requires IntelliJ IDEA Ultimate. Do you have it installed?

Nope =/
