How to use the scrapbook.scraps.scrap_to_payload function in scrapbook

def decode(self, scrap, **kwargs):
        """
        Finds the register for the given encoder and translates the scrap's data
        from a string or JSON type to an object of the encoder output type.

        Parameters
        ----------
        scrap: Scrap
