Actionable Notificatons created in iOS app

How (actionable) notifications can be re-used / shared once created in iOS app?
Once would expect those will be synchronized with HA and then shared to all iOS devices connected.
But I’m wrong right? If so, what was the motivation of the feature of app?

How can I use notifications created this way to send the same actionable notification to all members connected to my HA?

You can create notification categories in yaml in the ios component: https://companion.home-assistant.io/docs/notifications/actionable-notifications/#overview-of-how-actionable-notifications-work-on-ios

I know that.
But it’s not my question. iOS app allows to set up notification and use it without editing yaml. But then such notification works only with this particular phone only

The mechanism to share across devices is to define the categories in the configuration yaml.

Got it.
So notification editor built-into the application is only for experimenting purposes and provides no method helping in in-HA configuration? One could expect at least ready to copy&paste yaml code.

Feel free to subscribe to this feature request to see progress on export-as-YAML being implemented.
