Fade between two states

Hey first time poster and novice to Rive.

I have a setup where on mouse hover (button over state triggers), an animation plays.

When the button over state is false, i'd like it to fade (10 frames or so) back to the idle state.

So my setup is currently:

Idle ----------------> Animate in
^<----Animate back-----<

Had a look through all the docs and tried all the blends etc but can't work out how to do this.

Any help appreciated in advance!
