Help with iOS sounds

Trying to get an iOS Sound+Haptic Vibrate for when a certain trigger occurs. Everything works except I can only get the default sound.

#------------------------------
# Notify When Downstairs Motion Detected
#------------------------------
- alias: Send Notification When Downstairs Motion Detected
  trigger:
    platform: state
    entity_id: binary_sensor.downstairs_motion
    to: 'on'
  action:
  - service: notify.mobile_app_mgiphone
    data:
       message: "Downstairs Motion Detected"
       data:
        push:
            sound:
              name: "Alarm_Haptic.caf"
              volume: 1.0

only gives me the default iOS notification sound. However, if I replace the sound name with

name: "US-EN-Alexa-Motion-Detected-Generic.wav"

I correctly hear the Alexa voice. I’m doing something wrong with the iOS sounds but not sure what. Any suggestions?

Thanks!

Aaaand it took me 5 seconds after I posted this to figure out what I did wrong. I needed to Import the iOS sounds via the Home Assistant IOS App per instructions:
