I try to read a csv File from a Google Cloud Storage Bucket with Node (Google Cloud Functions).
The CSV File is zipped like this:

    const {google} = require('googleapis');
    const {Storage} = require('@google-cloud/storage');
    const {parse} = require("csv-parse");

    const storage = new Storage({
      projectId: 'XXX',
      keyFilename: './api-project-XXX.json'
    });


    const file = storage.bucket('pubsite_prod_rev_XXX').file("sales/salesreport_202406.zip");

    const content = await file.download({destination: "/tmp/test"}, function(err, file) {
      if (err) {
        console.log(err);
      } else {
        console.log("download successful");
      }
    });

How could I unzip and read the CSV File? Should createReadStream be used here? Does the file have to be saved in a bucket first or can it be unzipped directly?
