Viewing Z wave Mesh

What am I doing wrong? Trying to follow this guide and view Z wave mesh on my RasPi.

Added config into yaml

Added js to config/www folder

Restarted HA and I see it in the sidebar, but when I click it, i just see white.

Have you refreshed your browser?

(also, you should have just posted in the main thread for this feature rather than creating a new one)

Yes, refresh, restarted, etc. I posted in the main thread, thanks.
