UDM PRO Network App directory

[Crudelis98]

Hello guys,

Where is network app, protect app and so on stored on UDM PRO?
I found the: "/usr/lib/unifi/webapps/ROOT/app-unifi".

But this is only front end, it seems that js files from backend are not used on udm pro. So where is all the api hidden?

Thanks for help.
