Which ad_group_criterion fields to combine with ad_group_audience_view in Google Ads Beta API

Question

I am looking into the Google Ads (Beta) API and I want to query for the ad_group_audience_view values, but I am not sure which ad_group_criterion fields are relevant for this view.

E.g. for the topic_view, a related field in ad_group_criterion was ad_group_criterion.keyword.text:

SELECT ad_group_criterion.keyword.text FROM topic_view
