Graphic Slices not exporting

I want to create PNG files from graphic slices which Dorico appears to believe it’s doing but no PNG files appear in my destination folder, nor can I find any using the Finder (Mac Sonoma 14.6). I’m following the instructions in the documentation . . . is there some hidden setting I need to adjust to actually get it to export the graphic file?

Thanks, Derrek, That’s exactly what I’m doing, but no PNG file appears. I’ve still just got the .dorico file in that folder. Is there anything else I need to do?

OK, I changed the naming template and that seems to have solved it, fwiw

Thanks
