Content creation

Hi there. Hope you all are doing great. I just created an account to use H5P. I have seen some video tutorials... now I want to start creating my own content, but when I click on the option my account... in the menue that is next to the profile picture, it is supposed I can have a link to click to start creating content, however, it is not there. So where else can I find it? or what do I have to do in order for it to appear in that list of options?

I used to make interactive video and there were many programs along with that. Now, there are only few programmes. No interactive video. 

Is it possible to use existing Course Presentations when using the branch scenario? or possible to upload them somehow?
