Moving App to New Computer

Hi there, I recently was given a new computer at work. On my old computer (which I still have), I have an application for Google Tasks that appears to be native. It lives in a folder called “Chrome Applications.” I’ve been trying unsuccessfully to move this app to my new computer or download it again but I can’t find any traces of this being available. Does anyone know what I’m doing wrong and how I can get the app back on my new computer?
