Glide + Google Analytics || Interpretation of Events

Hi Glide Team,

I have integrated Glide with Google analytics and these are the statistics after a week. Find the snapshot below. Some of the actions are defined with names such as page_view, screen_view, user_engagement etc. Is there a Glide documentation on what these mean and how to interpret them? For example, under Scroll event, there is a count of 12049. How to interpret it? I do have a broad idea, but wanted to be sure. Thank you.
