Defines actions to be applied to a[template presentation](https://developer.android.com/reference/kotlin/android/widget/RemoteViews.html#).

It supports 2 types of actions:

1. [Actions](https://developer.android.com/reference/kotlin/android/widget/RemoteViews.html#)to be applied to the template.
2. [Transformations](https://developer.android.com/reference/kotlin/android/service/autofill/Transformation)to be applied on child views.

Typically used on[custom descriptions](https://developer.android.com/reference/kotlin/android/service/autofill/CustomDescription)to conditionally display differents views based on user input - see[CustomDescription.Builder.batchUpdate(Validator, BatchUpdates)](https://developer.android.com/reference/kotlin/android/service/autofill/CustomDescription.Builder#batchUpdate(android.service.autofill.Validator,%20android.service.autofill.BatchUpdates))for more information.
