Missing content folder and h5p.json
I've created my own h5p content-type (based on the interactive video) but when I import it, Wordpress tells me that the content-folder and the h5p.json file is missing.
I'm using "h5p pack -r h5p-own-type" command to build, but when I check the content of the created h5p/zip file, there's no h5p.json or content folder added. So I wonder how I can fix this? The "Get help" link doesn't help me that much and I also already checked out that other threads here in the forum without success. Do I need to add something in my library.json or how these files are created?
I also tried to "rebuild" the "h5p-interactive-video" using "h5p pack -r h5p-interactive-video" command, but it also doesn't contain the content folder and h5p.json file. Regarding the h5p.json file I found this page: https://h5p.org/documentation/developers/json-file-definitions
But I wonder if I need to recreate the h5p.json file even when trying to rebuild a standard h5p content type like the h5p-interactive-video and if so, where do I need to place it?
