Apple MPP opens via API or Webhook

I need the list of unique openers deemed Apple MPP Privacy opens for every campaign. We know we only see MPP opens via webhooks if there’s an accompanying click. That won’t work. We know we can download the list out of the ActiveCampaign UI, but it’s manual. That won’t work. Looking at the API we only seem to get 20 per page and there’s not an option to limit to just Apple Privacy opens. Anyone else have any luck with this?
