Squashing an object on Adobe Animate

Hey guys! I'm trying to use Adobe Animate to animate an object which squashes when the user clicks on the screen. I'm aware of creating an Instance with the object, naming it, and using the Wizard option (in a HTML5 Canvas Doc) to produce simple code. However the drop-down menu doesn't have the options i'm looking for. Does anyone know how, or the exact code I would need, to create an animated object which shrinks down when clicked, and continues to shrink the more you click it?

Thank you so much, really appreciate it.
