how to list italicized words

I was hoping AI Assistant could parse thru an open PDF and list all words that are italicized. Apparently it can't do so, further, after trying different approaches to asking the same questions, it said I'm suspected of attempting prohibited queries. I can open the PDF in Word and ask it to search for italics, and it will give me what I want....but it has always been able to do this...apparently AI isn't yet ready to provide such a simple request. Any ideas?
