Branching Scenario

Hello my friends!

First I would like to know if it is possible to expand the functionality of the branching scenario, as my goal is to add conditionals on the branches.

If it is possible to edit this way how can I do it? I have a lot of experience with HTML, CSS and Javascript. However, so far I am not able to run and edit the H5P libraries. I haven't really found a tutorial that clearly explains this.

The question is, how can I edit, run and test an H5P library?

Do you have any step by step?

Thanks

I wanted to create a branching scenario, but when I try to create a content, they only show me 12 types of content, do I need to update my account or something to get all the content? I am from Colombia.
