[Idea] An option to get notified when a game in my Steam Wishlist becomes available in some subscription service?

[bagarwa]

Say I have some 50 games in my Steam wishlist. None of them are currently on any game subscription services. Two months later, game ABCD becomes available on GamePass and XYZ becomes available on EA Play. I'd like to get a notification of sort about it. Maybe a native notification in the browser / windows, or via email. For the latter, willing users will have to share email id with the extension.
