Gmail Auto-Clean Script Needed

I need a small script that signs in to my Gmail account every five minutes and wipes everything sitting in the Spam and Trash labels. It will run on a Windows machine that stays on 24/7, so feel free to lean on Task Scheduler or a bundled loop/timer—whatever keeps the five-minute cadence consistent...
