Identifying galaxies in images is not the hard part of finding galaxies. I assume that they already have software that does that because galaxies are easy to identify because they are blobs. The hard part is taking the images with lots of galaxies. Most telescopes have a narrow field of view and they are busy so can't survey the whole sky. Rubin Observatory in Chile is going to survey sky every few nights. The Roman Space Telescope will be wide-angle Hubble.
