On a Mac 'Reveal in File Browser' makes nothing according to my testing (M2 Mac, macOS 13.7.8 Ventura). If I understand correctly, it should reveal the original files for the currently selected thumbnails. Either this is a bug (see post Bug: Finder crashes upon clicking "Reveal in File Browser", albeit my Finder does not crash, there is just no file(s) revealed in the Finder) or then I am asking for a new feature for Mac, i.e. add pop-up menu command 'Reveal in Finder'.
