[FedCM] Updates in Chrome 142 & New channel

[FedCM developer newsletter]

Hello FedCM newsletter subscribers!

We're continuing to improve FedCM based on your feedback, and we have a new feature to share.

New feature

From Chrome 142, IdP can opt to display the iframe's domain in the FedCM UI when the Relying Party (RP) is embedded as a third-party iframe on another site. This feature enhances transparency for users when they are signing in to a service that's embedded on a different website.

Learn more about the feature in the blog post. Read the documentation for implementation details.

New updates channel 

Note that all major FedCM update announcements are now published on the Chrome blog. Follow the blog to ensure you stay up-to-date with the latest changes.
