Sorry but i can't post a comment to your question above because of missing reputation, so I will include it in this answer.

Do as stated above by generating a signed Url, but instead of using the service-account.json I think you have to use the serviceAccountKey.json which you can generate at (replace YOURPROJECTID accordingly)

https://console.firebase.google.com/project/YOURPROJECTID/settings/serviceaccounts/adminsdk

Example:

const gcs = require('@google-cloud/storage')({keyFilename: 'serviceAccountKey.json'});
// ...
const bucket = gcs.bucket(bucket);
// ...
return bucket.upload(tempLocalFile, {
        destination: filePath,
        metadata: {
          contentType: 'image/jpeg'
        }
      })
      .then((data) => {
        let file = data[0]
        file.getSignedUrl({
          action: 'read',
          expires: '03-17-2025'
        }, function(err, url) {
          if (err) {
            console.error(err);
            return;
          }

          // handle url 
        })
