in CLI tool how to pack only contents, not a whole library?

On https://h5p.test.schulcloud-thueringen.de/content-types-and-applications when we click the Re-use button on any of the example contents, we get the "contents" only, without the actual libraries. For instance, clicking on the Re-use button at https://h5p.test.schulcloud-thueringen.de/dialog-cards#example=619 we get this kind of package:

In the CLI development folder on my local computer, the H5P contents that are created reside (for example) in "C:\my_first_h5p_environment\content". Each content looks like this:

What I want is a CLI command to pack the h5p.json and content.json files and the audio and images folders to a minimal h5p contents zipped file (excluding of the sessions folder which is not needed).

Any ideas anyone?
