Voice Assist initiate conversation / prompt on mobile app?

Good people - not sure if what I am trying to do is possible or not, some docs seem to suggest it is, but when I start, I am not getting very far…

I want HA to ask me a question, same as a mobile actionable notification does, but using speech.

For example, when the mobile device gets within a certain zone, I want the companion app to ask me if I want to open the gate. I respond yes or no, and magic happens.

This is working, sort of, with an actionable notification, although notification on iPhone is rubbish / clunky, if you click in the wrong place, it’s gone, and it’s awkward to do when driving.

Would be so much better if it just asked me…

Docs suggest I need a HA voice device in the house, which I don’t want, unless it’s a requirement to make this function work on the companion app.

Am I asking too much?

There is an ask command. I forget what is is but see below thread

Thank you - yes I saw this command, but all the examples seem to be running this on voice satellite hardware rather than the companion app offsite.

Sorry

Not sure if you can do this on IOS.
Android may be possible.

Resoonse File will need to be remotely accessible
