Support for web push notification as a transport mechanism

[numatay]

Hello there,
According to the specification, transport mechanisms such as SMS, email, and hardware devices can be used to enable OTP in a browser. Currently, the SMS option is being explored extensively and I was able to implement OTP retrieval on Chrome with provided code snippets. I believe web push notifications could serve as a good alternative to SMS transport in the mobile web landscape. Is there any plan or ongoing work to add web push notifications as a transport mechanism to deliver OTP on mobile browsers via web push notifications?
