Hi Jakub,
Thank you for reaching out to the Google Ads API support team.
Kindly note that your understanding is correct that the Google Ads API currently does not use the term "AD_IMAGE" for assets within Performance Max campaigns. Instead, it uses the concept of Asset Field Types. I suggest you refer to the documents Mutate and Performance Max - Asset Groups to get more information.
I hope this helps. Kindly get back to us in case of any further queries.
