PushToTalk framework - New Call-like countdown and PTT button

Recently, we have started seeing this countdown in the dynamic island and it enables kind of listening mode and app completely loses the talk button. This is seen very recently and I cant make what it really is. I would like to know what this UI is and how I can bring back talk button.
