Odoo 14 - Override method associated with "Discard" button

Question

I need to run additional commands after the Discard button has been pressed.

I know how to do this with Save button:

@api.model
def create(self, vals): 
    # my code before create
    result = super(MODEL_NAME, self).create(vals)
    # my code after create
    return result

But I'm unable to find method associated with "Discard" button. How is it called?
