Requiring successful completion of activity within interactive presentation to proceed to the end slide (branching scenario)

As an author, I would like to be able to make an educational choose your own adventure game or escape room by making progression within a Branching Scenario contingent on successful completion of an activity (e.g. fill-in-the-blanks, drag and drop, etc.) within an interactive presentation (though this would presumably be extended to interactive video, I just haven't been using that). One way this would be possible is demonstrated through this blog post: https://www.olivertacke.de/labs/2019/09/04/an-unexpected-demo/, where the player can only progress once they reach the end of the interactive presentation, and they cannot progress to the end of the presentation until they meet a success criteria for the activity. I understand the former feature has already been implemented since I last asked about this 6 years ago on a thread where someone requested something similar (https://h5p.org/comment/29963#comment-29963) but the latter hasn't. It looks like there are others asking for this feature, like this one: https://h5p.org/node/1301262#comment-form.

This feature is what is holding back the branching scenario content type from being used for a much wider range of games and uses. We currently use a branching scneario for an educational game year after year very successfully, but it can't be expanded and become truly impressive until the player can progress based on their success with an activity - the workaround we've used for what we need to achieve is too cumbersome, and requires the player to complete the activity and then enter the same answer again in a multiple-choice format in order to gatekeep progression.
