I don't understand what you're saying. It absolutely is behind a permission prompt. If you go to the demo site: https://idle-detection.glitch.me/ https://idle-detection.glitch.me/ and click "ephemeral", it shows a prompt next to the address bar saying "idle-detection.glitch.me wants to know when you're actively using this device" and has buttons for "block" and "allow". So I don't know how "it really isn't" could be true in this case.
