Oddly enough if you enable it as a "quick action", when you run it, Finder creates a file in the same directory as the image containing the OCRed text (and named according to the first line of OCRed text).

I went back into my shortcut and Shortcuts added a pseudo-action "Stop and output <copy to clipboard>; if there's nowhere to output: <Do Nothing>", and I would think that "Do Nothing" would mean don't create a file, but I guess Quick Actions has some kind of special meaning given that all the other ones seem to be intransitive actions, implying that the user wants a file as the output.
