Ios notification (via home assistant for ios)

hi all,
i’ve installed and setup home assistant for ios in my iphone xr, in hassio i have installed the integration home assistant for ios.Now i was aspected that in items or somewhere else, there was a notify.ios_ but i’m unable to find it… I also tryed with dev-service, but there isn’t any service called notify.ios_… looking in the log i found this:

The notify.ios platform was loaded but no devices exist! Please check the documentation at https://home-assistant.io/ecosystem/ios/notifications/ for more information

but the ios.conf file is missing (i tryed to create it manually but it remain empty)… I can’t understand what’s missing, iphone says that the notify platform is loaded and it can retrieve the push id
