Offline Apple Push Notification

Hello all,

if Home Assistant has no internet connection (internet outage for example) and the companion app is on the same IP network (wifi), is there a way for the companion app to receive push notifications anyway?

I know it’s technically feasible (offline Apple Push Notification are a feature offered by some other products I have seen) but I don’t know if Home Assistant supports it and if yes, if there are specific requirements.

cheers
