Invoke chat window from anywhere

[SPL3S]

Is there a way to invoke chat window with chosen user form anywhere in website?
lets say I have a button placed somewhere
<a href="{{ url('/chatify/'.$userId.'/') }}">Message user</a>

and once clicked it would open chat window with the selected user?

This actually already working, I had issues with Debugbar messing with the pusher events and thus it didnt work.
