I have thousands of new-video notifications on YouTube. I’m a crazy power user, and I want to (at least) look at all of them, preferably save them for later in a big list (like exporting bookmarks).

How can I get my unread notifications (as an end-user) using the API?

There don’t seem to be any extensions for this, and I don’t want to click on the bell, lest the page load “only” a few hundred videos before some loading-error hits. (This has happened to me at least once on some website, although I’m not sure if it was YouTube or not.)
