Implementing 3-State Buttons for Touchscreens

Hello! What’s the best way to implement a button that works for pointer events and is compatible with touch screen tapping? My proof-of-concept (POC) button has three states: 1. default, 2. small (pointer over), and 3. flat (pointer down).

I’d like this button to work on touchscreens as follows: 1. default, and 3. flat (on touch), with it reverting back to the initial default state. Ideally, it would also play the 2nd state (small) briefly in between, if possible.

Currently, tapping the screen returns the user to the 2nd state instead of 1st, because it seems pointer up is not functioning with tapping?

So yeah, I’d like to know how to professionally implement a 3-state button that works seamlessly on both pointer and touchscreens.
