which I believe means that every call to `getDisplayMedia()` will prompt (or auto-deny). Since the result object from `getDisplayMedia()` can't outlive the tab, that caps the lifetime of the capability. It probably wouldn't be a good idea to additionally specify a wall-time limit on how long someone can share their screen.
