Add or remove audience segments (remarketing lists, affinity, in-market, life events, detailed demographics, custom audiences, and combined audiences) at the campaign or ad group level with Targeting or Observation settings. Use the `gads_list_audience_segments` node to find segment resource names. Note: this operation doesn't work with PMax and Demand Gen campaigns, which use Audience Signals instead.
