Make (`ocrmypdf`) command run in terminal AND include input name in that of the output

I have this line inside a Dolphin service-menu file that contains many other commands for PDF processing: Exec=bash -c 'f="%u"; ocrmypdf "$f" "${f%.pdf}_ocr.pdf";' It has the advantage of giving an output file of the form MY_PDF_ocr.pdf, thus keeping the name of the input file. But I would prefer to have the command running in terminal (konsole) so that I see the process. For that, I can use the line: Exec=konsole --noclose -e ocrmypdf "%u" ocr_en.pdf but without the output keeping the name of the input. A line like Exec=konsole --noclose -e ocrmypdf "%u" "${%u}_ocr.pdf" does nothing. How to adjust the ocrmypdf so that the command is run in konsole and the output includes the name of the input?
