Dismiss firefox update popup with WebdriverIO

Question

I want to dismiss this popup when I'm running my tests with webdriverIO but I'm not able to do it. I'm using chimp to run my tests

I tried with browser.alertdismiss() but it didn't work. Also, I tried using this NPM package and adding this configuration but seems that firefox it's not taking that profile

My configuration file

// wdio.conf.js
const config = {
  // ...
  services: ['firefox-profile'],
  firefoxProfile: {
    "app.update.enabled": true,
      "app.update.auto": true,
      "app.update.silent": true,
      "privacy.popups.firstTime": true,
      "update.showSlidingNotification": false,
      "update_notifications.enabled": false ,
  },
  // ...
};

module.export = config;
