Get url of uploaded file in firebase storage

Question

I am uploading a file to firebase bucket with this code

 const uplaodTask = await storage.bucket('example.appspot.com').upload('/temp/out.png', {
   destination: `/${jobID}/results/${filterName}.png`,
});

How can I get the public url of the uploaded file? I tried the following code but it's not working

 uplaodTask.getSignedUrl({
  action: 'read',
  expires: '03-09-2491'
}).then(signedUrls => {
  console.log("URL: ", signedUrls[0])
});
