Teams-awake

Stay green in Microsoft Teams – automatically. Teams Awake is a lightweight Chrome extension that prevents Microsoft Teams from setting your status to "Away" when you're actually still at your computer. It works by simulating harmless user activity (like mouse movement and window focus) in open Teams browser tabs – so you stay "Available" without having to constantly wiggle your mouse. This extension does not collect, store, or transmit any personal data. It only interacts with Microsoft Teams tabs on your local browser.
