Course Presentation

I am attempting to install the Course Presentation content via the H5P hub on a Wordpress site. However, the package cannot be validated as it is missing the library H5P.InteractiveVideo 1.26.

I did try to install the Intervative Video content but this only added Interactive Video (1.27.8) to the library and not the required package for the course presentation.

Where can I obtain the correct library file for the InteractiveVideo 1.26?

When I updated to CKEditor5 in the Course Presentation, I noticed that the creation of interactivity slowed down, ie. it happens that the browser suddenly blocks. Does anyone have a similar problem in Presentations? No errors in error log file.

H5P in WordPress
H5P 1.16.0
WordPress 6.6.2

I created and saved content last night but this morning content is missing. I saved and copied the content to clipboard but now its missing. How do I find my content?
