[question]: Android import issues with Notification Service Extension while migrating to v5

[TheMeanCanEHdian]

How can we help?

I am attempting to migrate to v5 but running into an import issue with the notification service extension.

I am getting unresolved reference when attempting to import IDisplayableMutableNotification, INotificationReceivedEvent, and INotificationServiceExtension as shown here.

I haven't seen any migration steps for the service extension. Is there something obvious here I have likely missed? I am doing the imports in a Kotlin file but do not believe that matters here.

Here is a screenshot of a minimal version of the file that is failing.

Any help would be appreciated.
