Firebase Analytics Debug View for the Web

I tried successfully to Debug by using instructions (for Web) at https://firebase.google.com/docs/analytics/debugview?authuser=0#enabling_debug_mode.

After installing Google Analytics Debugger, there appears an icon of this extension, next to address bar. This icon helps on enable the extension for the page.

I quickly browsed through the documentation guide, and reference docs and indeed don't see any way to enable debug mode for a web client. You might want to file a feature request.

Update (20191008): the functionality to have debug mode in web clients does exist, but there is no public API yet. I will update here when a public API to enable debug mode is available.

Update (20200210): the best I've found so far is to use the Google Analytics Debugger Chrome extension.
