Okular highlight other than text

Very often, the OCR functionality wrongly identifies the text in my PDF books, or worse the books are not OCR scanned. In both cases, the highlight functionality of Okular proves insufficient for me. I have attached an image showing one case of the former problem for me. Is there a workaround for this? If not, how can I request for a change in the highlight annotation to switch off text-only highlight (as in edge)?
