Trigger HomeKit scene from actionable notification on the client?

Is it possible to somehow trigger a HomeKit scene from an actionable notification without hitting the HA server? I don’t think it’s possible to do a cross-app action like that directly…instead the HA app would have to implement a sort of relay…so the action would hit the HA app, and the HA app would in turn trigger the HomeKit scene. Is such a thing possible or has it been considered?

The reason I want to do this is so I don’t need to have my HA server exposed to the Internet. Everything else I need to do externally I can do through HomeKit, so HA stays nice and hidden and secure…but it would be nice to be able to use actionable notifications externally too. Thx!
