Kitchenaid KBFS22EWMS7 Defrost Thermostat

I’m looking for a bimetal defrost thermostat compatible with a kitchenaid model kbfs22ewms7 fridge. The part looks like this https://www.appliancepartshq.ca/part/15339580 , but I need to verify the correct part for my model. Unfortunately, that part doesn’t seem to show on any of the part schematics that I’ve found online. Any help would be greatly appreciated.
