Ability to create a button in live activities

[alexw23]

Describe the feature

I’d like to be.able to create a button in the liveactivities for iOS.

Use cases

I could pause a washing machine, pause a movie, resume a device, unlock a door.

Examples

A single dynamic button on the right hand side (circular with a centred icon which can be specified via MDI)

This would be specified as a button entity in the HA config.

Anything else?

Haven’t considered is how a result would be reflected.

Is it that pressing a button linked to a live activity must produce another notification, but then what if that notification is throttled? How would a user know there was an outcome?

I'd love this feature too. Being able to acknowledge a finished laundry cycle directly from the Live Activity would be especially useful.

Related: #4638 asks for the same thing and proposes reusing the existing actionable-notification actions (same action/title/icon keys and mobile_app_notification_action event) for Live Activities. It might make sense to merge the two so the votes are counted in one place.
