Using notify group to send HTML notifications to Android and plain text to iOS

I’m trying to send a notification to everyone in the home. We’ve got some Android users and some iOS users. For the Android users, I’d like to use some HTML in the message. For the iOS users, I’d like that to be omitted (since it’s not supported).

Is there any way to do this while still using notification groups?

configuration.yaml:

notify:
  - name: ALL_DEVICES
    platform: group
    services:
      - service: mobile_app_pixel
      - service: mobile_app_iphone

Script:

alias: AQI Notification
mode: single
sequence:
  - alias: Send notification
    service: notify.ALL_DEVICES
    data:
      title: AQI Alert
      message: >
        AQI is <span style="color: {{ states("sensor.aqi_color") }}">{{
        states("sensor.aqi_string") }} <b>{{ states("sensor.aqi") }}</b></span>.
      data:
        color: "{{ states(\"sensor.aqi_color\") }}"
        channel: Air Quality
        tag: aqi-alert
