Unable to create buttons in iphone notification

I can receive notifications together with my camera image, but can’t see any buttons, regardless of how I change the configuration.yaml file.
My file is …

default_config:
# Text to speech
tts:
  - platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
ios:
    push:
    categories:
        actions:
            identifier: 'LEAVE_PARCEL'
            title: 'Please leave the parcel'
        name: 'cameras'
        identifier: 'camera'

Then in developer tools I can run a service notify.mobile_app_jims_phone with …

data:
  actions:
    action: LEAVE_PARCEL
    title: heating
message: hello       

I get the notification but not any button.
If I go into the iphone app settings I have no synched categories - is that why? Some articles say I have to reset push settings but I don’t have that option in my settings?

Hi

I have now got the synched category working, but in my developer tool test service I can’t get both the camera AND the buttons working at the same time.
How do I specify 2 categories, one for the camera, one for the button?
The two categories are

data:
  push:
    category: "alarm"
  actions:
    action: LEAVE_PARCEL
    title: heating

and for the camera

data:
  attachment:
    content_type: jpeg
  push:
    category: camera
  entity_id: camera.doorbell

The YAML you are defining above is not formatted correctly; categories are an array (the - decoration) and actions for categories are defined inside of them. Please see the documentation for examples
