where are the tap featues of the Airpods on the Airpod Pros?
Tap on AirPods is replaced with a press on the stem (squeeze) on AirPods Pro.

On either AirPods Pro stem:


Single press for play/pause
Double press to skip media (next song, etc)
Triple press to play from start, or if at start, previous media (last song, etc)
Hold stem for the custom action in Settings, i.e. switch listening mode or start Siri.
