How to use the @wdio/allure-reporter.addAttachment function in @wdio/allure-reporter

if (test.state === 'failed' || (test.state === 'passed' && config.saveAllVideos)) {
      const filePath = path.resolve(this.recordingPath, this.frameNr.toString().padStart(4, '0') + '.png');
      try {
        browser.saveScreenshot(filePath);
        helpers.debugLog('- Screenshot!!\n');
      } catch (e) {
        fs.writeFile(filePath, notAvailableImage, 'base64');
        helpers.debugLog('- Screenshot not available...\n');
      }

      const videoPath = path.resolve(config.outputDir, this.testname + '.mp4');
      this.videos.push(videoPath);

      if (config.usingAllure) {
        allureReporter.addAttachment('Execution video', videoPath, 'video/mp4');
      }

      const command = `"${ffmpegPath}" -y -r 10 -i "${this.recordingPath}/%04d.png" -vcodec libx264` +
        ` -crf 32 -pix_fmt yuv420p -vf "scale=1200:trunc(ow/a/2)*2","setpts=${config.videoSlowdownMultiplier}.0*PTS"` +
        ` "${path.resolve(config.outputDir, this.testname)}.mp4"`;

      helpers.debugLog(`ffmpeg command: ${command}\n`);

      this.ffmpegCommands.push(command);
    }
  }
