iCloud Passwords Extension for AI Browsers Comet and Dia

I have switched to Apple iCloud Passwords App a few months ago. Which is great because its highly integrated with a lot of what I do.

BUT it's very frustrating that the new AI Browsers I am using (Comet Browser by Perplexity and Dia Browser by Arc) are not supported by iCloud Passwords Extension. Even though they are Chromium based and can install the extension.

What is the plan about those browsers? When will they be supported?

Thank you in advance,

Lin
