Drawings on top of a code block

[pgiannikos]

I'm trying to apply annotations (arrows, shapes, etc) and marker drawings on the top of a code block and it does not seem to work. Any ideas how to eventually do it?

Thanks

You can embed it as an image and that way yes, although if you want to have it as it is there, a trick you can do is increase the transparency and you can see the drawings and elements.
