how could i make a rive animation responsive?

Loving Rive a lot, trying to make a rive animation that once it would hit a breakpoint(mobile) 350px width it could swap out state machine
for another one, could I achieve this with a listener input that tracks the canvas width I saw this tweet and would like to figure out how it was done.
