您可以使用受众群体触发器完成下面哪项任务？

Audience triggers allow you to create new events when a user meets the criteria for a specific audience. This is useful for tracking key user segments and their behaviors. For example, you could define an audience of "High-Value Customers" and then create an event, "High-Value Customer Achieved," to fire when a user enters that audience. Creating new audiences based on triggered events is incorrect because audience triggers create events based on audience membership, not the other way around. Creating new events based on existing event parameters is a function of event modification or creation, not specifically audience triggers. Creating new audiences based on predictive metrics is a feature of predictive audiences, not audience triggers.
