I upgrade my app from vue2 to vue3 in which @PropSync() is not working How do i resolve this?

import { Component, Prop, PropSync, Vue } from "vue-facing-decorator"; @PropSync("rawFromParties", { type: Object, default: null, }) syncedRawFromParties!: { [P: string]: ISelectListItemGroup[] } | null;

This code is not working now
