How do I write a mathematical arc in latex like in the picture? I tried using the notation: \(\wideparen{A B}\) or \(\arc{A B}\) but it can't be displayed. Is it necessary to add an additional package?

Hi,

I noticed that H5P file downloaded from H5P.org with "Reuse" button does not contain any dependency folders. Archive contains only:

• h5p.json
• content folder

Is this a new feature or a bug?

I would like to create an interactive video, where the fill in the blank has no wrong answer. It is a self-reflection style question so there is no right or wrong answer. Is there a way to do that? Is there another interaction that allows for that? Thanks!
