"Pay with Apple Pay" button

I want to you use "Pay with Apple Pay" button on my website.
As per the documentation here https://developer.apple.com/design/human-interface-guidelines/apple-pay/overview/buttons-and-marks/

I see a Pay with Apple button as a type, but in the css I do not know what type will show this kind of button.

Is this button yet not available or I am missing something? Can somebody help here?
The "pay" button type is not available on the web. Please see https://developer.apple.com/documentation/apple_pay_on_the_web/displaying_apple_pay_buttons for which types are available on the web.
