How to use cdn unpkg in dashplot

i am trying to add external js static files but not able to get it working.

when i set

app.css.config.serve_locally = False
app.scripts.config.serve_locally = False

I GOT
WARNING: dev bundles requested with serve_locally=False.
This is not supported, switching to serve_locally=True

I have kept debug=False in run_server.

Is this the right way?? If not please suggest…

Thanks
