New Incoming Call UI in Testing for Google Phone App

The Google Phone app appears to be testing a new incoming call UI that ditches the draggable accept or reject button in favor of dedicated accept and reject buttons, similar to the iPhone dialer and various Android OEMs such as Samsung. The 'Answer' button is green on the right under the quick 'Message' toggle, while the red 'Decline' button is on the left. This change has arrived with Google Phone v145.0.672690850 but seems to be a limited test.
