[GA4] Enhanced measurement

Enhanced measurement events are only collected for websites (web data streams) and they don't count against the limit of 500 distinctly named events.

Enhanced measurement lets you measure interactions with your content by enabling options (events) in the Google Analytics interface. No code changes are required. When you enable these options for a web stream, your Google Analytics tag starts sending events right away.

Before turning on the enhanced measurement feature, be sure you understand each option and what data will be collected. You can also turn off specific measurement options in settings.

You're required to ensure that no personally-identifiable information is collected.
