In the settings.py
ASGI_APPLICATION = '_keenthemes.asgi.application'
usually ASGI_APPLICATION = 'appname.asgi.application'

But app name is inconsistent

In the installed apps section app name is given as dashboards.apps.DashboardsConfig
by folder hierarchy i can consider dashboards as app name

so possible values for ASGI_APPLICATION are
ASGI_APPLICATION = 'dashboards.apps.DashboardsConfig.asgi.application'
ASGI_APPLICATION = '_keenthemes.asgi.application'
ASGI_APPLICATION = 'dashboards.asgi.application'

Which is correct
In asgi.py

"""
ASGI config for _keenthemes project.

It exposes the ASGI callable as a module-level variable named ``application``.

For more information on this file, see

I think I have configured all the files correctly
Please let me know the right app name
Any insights will be of huge help
Thanks
