AUTOMATIC submission of answers in a interactive video?

I get asked a lot why answers aren't being submitted in an interactive video. After all, the user has done a lot of work sitting there watching a video and interacting with the content that is overlayed on the video. Little do they realise that the tiny obscure star icon at the end of the video bar is in fact a button that you can and must press. It doesn't sing or dance or animate in any way to alert your attention to it, so why would you click it? - unless you had secret insider knowledge that it is in fact something you have to do IF you want your answers to be recorded. Any of course, nobody would ever want their answers recorded would they?

1. My users don't know the star is clickable.
2. My users complain their responses aren't saved.
3. Why can't the interactive video just submit automatically at the end?

This content type just has so many shortcomings like this. The secret star button is the icing on the cake though - there isn't even a tool tip to indicate that it does anything. There's an "aria label" in the code which reads "Open summary dialog". Nobody knows what a summary dialog is. "Dialogue" is a word that means "a conversation between two or more people" - it doesn't have anything to do with "here is the secret button you must press".
