H5P on smart board

I'm interested in which events use the content types "Drag and drop" and "Drag the words" when dragging objects. Are these standard events: dragover, dragstart, drop?

I ask this because I am trying to project h5p interactivity on a smart board. I use an OpenBoard program (https://openboard.ch/index.en.html). Every interactivity is successfully realized only I have a problem in "Drag and drop" content type. No object can be moved at all. I would rather say that the problem is in the OpenBoard program itself, and not in h5p. But I'd better ask if anyone has encountered this before.
