So I just bought the Queer Games Bundle 2021. Now as we all know, the only way to claim games that you've paid for is to go through them and click the "download" button, otherwise they won't appear in your library.

However, some of the games in the bundle don't have a download button. They only have a "Play in Browser" button, and clicking on that doesn't add the game to your library. So basically any game in a bundle that doesn't have a "Download" button can't be added to your list of owned games.
