icon size adjustment at least on mobile

I've been told that currently there is no way to make the icon smaller on mobile devices.
I have tried about 14 different ways to override it even js injection into the iframe.. I can move the icon but not resize it.
the icon on an average phone screen is crazy huge imho.
Please allow for mobile icon resizing or even another icon option with width/height definitions like a vertical rectangle attached to the right like many other chat offerings.
