Tampermonkey script to claim all of the items within a Bundle on Itch.io

Is there a way to edit this code so that it grabs all the free to claim games on itch.io/games/on-sale?

That would require an at least one entirely new script. It would need to parse the information for any game that has a price of $0 and open that game's page.
There's possibly an API way to do it but that's not something I'm familiar with.

Idk if its exactly how you want it (for only sale items), but something like that does already exist. https://github.com/Smart123s/ItchClaim
