Is the Google Tag (Initialization) always required for GA4 event? If we have tracking code manually added to the site, and we add the Google Tag will it duplicate the tracking? Thanks very much.

Hi Julius, I'm completely confused by 'mistake #1', as it does not make any sense to me. If your GA4 configuration tag fires before an event, then that event isn't captured/sent to GA4? Because of this, how is GTM supposed to work at all exactly? Can you please redo mistake #1 as a completely separate and new video? I'm completely lost on your description and examples provided.
