Is there any way to add mouse over event to display image on hover over highlighted text?

Hi everyone!

I have a PDF document. I have need to show image on mouse hover over some text I have highlighted and hide image when no mouse is hovering on the text.

Is there any way to achieve this? Thanks in advance.

This would be a feature of your PDF viewer like Acrobat, over which there exists not control. This a thing outside PyMuPDF's scope.

One could additionally add a link (pointing to nowhere) at places where there exists a highlight annot, that would at least change the cursor to the hand symbol.
I know of no way to influence the cursor appearance dynamically given a specific viewer.
