Error on Unzipped

[jaeverba-javana]

Hello, i have te next code:

import { unzipSync, strFromU8 } from 'fflate';

const zipFile = await Deno.readFile("./svg.zip");
const zip = fflate.unzipSync(zipFile);   

console.log(strFromU8(zip['icon-whiteboard-xmark-semibold.svg']))

// the console prints: "[B@6173c720"

I'm waiting for getting a SVG element, but get what seems to be a java class reference.
Maybe the pollifil is not working as spected

PD: sorry if my english is not pertect, i'm learning
