Whisper voice effect with Alexa Actionable Notifications?

Configuration Voice Assistant

Has anyone managed to get Alexa’s whisper voice effect working with Actionable Notifications?

I use the following nodes separately in Node-Red

Action node to call an actionable notification
Action
script.activate_alexa_actionable_notification
Data

{
    "text": "test message.",
    "event_id": "ane_testevent",
    "alexa_device": "media_player.kitchen_echo"
}

And an action node for the whisper effect
Action
notify.alexa_media_kitchen_echo
Data

{
    "message": "<amazon:effect name='whispered'>test message</amazon:effect>",
    "data": {
        "type": "tts"
    }
}

Each works fine on their own, I can use actionable notifications, and I can broadcast messages with the whisper effect.

However, I’d like to be able to call an actionable notification with the whisper effect, but I can’t figure out how to combine the 2 nodes since they use different actions and data.

Has anyone ever tried this, or has an idea if this would be possible? Thanks in advance.
