import { getOwnEnumerablePropertySymbols } from "https://deno.land/x/chai@v5.1.2/lib/chai/utils/getOwnEnumerablePropertySymbols.js";
.getOwnEnumerablePropertySymbols(object)
This allows the retrieval of directly-owned enumerable property symbols of an object. This function is necessary because Object.getOwnPropertySymbols returns both enumerable and non-enumerable property symbols.
