PWA sync either by sync chain or manually

Is it possible to sync PWAs? I see the option in Sync settings, but no evidence of it working between devices, even those running the same OS. If it is not possible to do so using the sync chain, does anyone know how to move web apps between devices manually? I am most interested in duplicating the webapps across macOS, but also would like to sync them between Linux computers too (running Zorin). Any pointers appreciated!
