Content creation

I would like to use the questionaire in moodle. It is in the installed libraries overview. It is turned on, However I can not find it when I create a H5P activity. I would like to be able to poste a questionaire at the end of an interactive video for example.

I am new to H5P and may be missing something (apologies if this is the case). We use Canvas and so it is my understanding that I need to create content on the h5p website and then embed it into my Canvas course. I am creating interactive videos, and I'd like to use some mathematical symbols or formulas in the pop-up questions. The editor does not allow any such thing however, not even super- or subscripts. Could anyone give me some guidance? Thanks- Petra
