python - Django import Error(from extras.plugins import PluginConfig)

Question

I'm new to Django and I try to develope a plugin for NextBox using this framework. To get familliar with it I'm using documentation from NextBox for this. My Problem is that I try to import a class as shown in the tutorial I get an Error that the package is unkown. When I want to install the package via PyCharm it seems to be the wrong one. Maybe someone of you can help me?

Doc: https://netbox.readthedocs.io/en/stable/plugins/development/

from extras.plugins import PluginConfig

class NextBoxUIConfig(PluginConfig):

In the IDE it says that extras is unkown after installing the package, .plugins is unkown as well as PluginConfig
