There are several features in Get Help beyond the primary feature of linking to a broken URL. You can sign in, you can rate your experience out of five, or you can send feedback. There is no Contents or Index, but there is a search box with a few suggested searches like 'How to install Office'. I tried searching 'how to copy paste' (without quotes) but "Your search did not match any solutions." It suggested I sign in to contact support. Closing the app is a little tricky because the minimise/maximise/close buttons are the wrong colour - white on pale grey.
Before closing the app, I selected a rating of 1/5, although my rating had been cleared upon reopening.

I just tried F1 in both Firefox and JetBrains Rider. Nothing. I wonder when that one disappeared. Though at least both have a proper online help.
edit: Trying it in all open apps, some kind of help opens in MS Teams, Discord, Outlook and Directory Opus (file manager).
The big legacy software suites still have actual help pages and PDF manuals, while the mainstream stuff just has a FAQ on their web page.
