Hi, I’m currently using a programmatic use case to deprecate an attribute and replace it with a new one. For instance, if I want to rename fromDomain to senderDomain, I can use the get function to retrieve the value. Since senderDomain doesn’t exist, the get function never gets called. Is there a way to achieve this using the electrodb?

export const emailEntity = new Entity({
  attributes: {
    from: { type: ‘string’, required: false },
    /**
     * @deprecated Use senderDomain instead
     */
    fromDomain: {
      type: ‘string’,
      required: false,
    },
    senderDomain: {
      type: ‘string’,
      required: false,
      get: (item, { fromDomain }) => item ?? fromDomain,
    },
  },
});
