WebIO Jupyter extension not working

Hi
I am trying to replicate the interactive plots examples using Interact.jl package (Tutorial · Interact) on a Jupiter notebook. But running into problem with detecting WebIO. This is the first time I had to use WebIO on my machine (Mac). Here is what I tried.

`using Interact, Plots, Mux

WebIO.webio_serve(page(“/”, req → ui), rand(8000:9000)) # serve on a random port
`
The error message says:

The WebIO Jupyter extension was not detected. See the WebIO Jupyter integration documentation for more information.

Following the link given for more information (IJulia (Jupyter) · WebIO), I have installing WebIO using the terminal command, restarted the Jupiter notebook kernel, re-ran the code. I am still getting the same error.
Any help is appreciated.

Are you doing this in a clean environment? Otherwise, what are the contents of the your environment?

The output for the following might be helpful:

using Pkg
pkg"status -m"

I didn’t understand what is meant by “clean environment”, could you explain this?
The output from

using Pkg
pkg"status -m"

gives a long list of packages, Below I give them . What should not be in that list?
