Google Analytics (分析) 4 的哪項工具讓廣告客戶即使在缺少可觀測的資料時，也一樣能模擬使用者歷程？

Consent Mode allows Google Analytics 4 (GA4) to model user behavior and conversions even when users decline analytics cookies. It adjusts how your Google tags fire based on users' consent choices, sending cookieless pings to Google. GA4 then uses machine learning to fill in the gaps in your data, providing insights into user journeys that would otherwise be unobservable due to privacy restrictions. Google Tag Manager (GTM) is a tag management system, not a data modeling tool. Enhanced conversions improve conversion measurement accuracy but don't address data gaps from consent. Private Mode is not a standard Google Analytics feature.
