Interact.jl widget in Jupyter Lab

Hi guys,

I am trying to using Interact’s widget in JupyterLab. But I was unable to get the widget working after I tried my best to install Interact and WebIO. I believe I had missed something. Thank you for your help.

using Interact, WebIO
#test
@manipulate for n in 1:10
    n
end

Running Node(:div, Node(:p, "I am a paragraph!", class="important")) from WebIO seems rendered.

I think the WebIO extension is successful added to the jupyter.
