What browser permissions does this timelapse tool require?
This tool requires two main browser permissions.
  1. Second, it requires permission to write files to your computer, which is requested when you click 'Select Directory'. This uses the showDirectoryPicker API.
  2. First, it needs permission to access your screen or a specific application window, which is requested when you click 'Select Stream'. This uses the browser's getDisplayMedia API.
