interactive book

I would love for content in Interactive Books, such as Interactive Videos, to resize when going into fullscreen. Alternatively, there could also be a fullscreen mode for child content types. As this user has already pointed out it seems impractical and unintuitive that there is no fullscreen mode for Interactive video within other Content Types.

I have the 30-day trial with Canvas integration. I am making an Interactive Book. The Essay content type is missing both in just adding it by itself and also in the Question Set. I have attached a screenshot. I saw another thread here saying to make sure it's installed again, but that was for WordPress. I'm on H5P.com creating this instead of directly in Canvas, so everything should be there.

Is Essay just not allowed in Interactive Book?

I hope this message finds you well. I am exploring the possibilities within the H5P Interactive Book and was wondering if there is a way to incorporate an interactive element, such as a interactive video or a branching scenario created in H5P, as part of an Interactive Book. Specifically, I am interested in:

1. Using such elements directly within the Interactive Book.

2. Referencing these elements through shortcodes or other methods. If this functionality exists, could you please guide me on how to implement it?
