How can I wait with processing further logic untill all request from batch are proceeded

  async processBatch(batch){
// requests: {
//     url: string;
//     userData: CrawlerUserData;
// }[]
    const requests = this.generateRequests(batch)
    await this.crawler.addRequests(requests)

    return this.processResults(requests)
  }
...
  async processResults(requests){
    ...
    for (const request of requests) {
      const userData = request.userData as CrawlerUserData
      if (userData.error) {
        this.statistics.incrementErrors()
        continue
      }

      if (userData.results) {
        ...
        await this.saveResults(userData)
      }
    }

    return batchResults
  }

import { createPlaywrightRouter } from 'crawlee'

export const router = createPlaywrightRouter()

router.addDefaultHandler(async ({ page, request, log }) => {
  const userData = request.userData as CrawlerUserData
  try {
    await page.waitForLoadState('networkidle', { timeout: 5000 })

    const analyzer = new AlertsProximityAnalyzer(userData, callbackCheckingIfDataExist)

    await analyzer.analyze(page) // executing callback

    userData.results = analyzer.results
    // Do I need to save the results here?
  } catch (error) {
    ...
  } finally {
    // Instead of closing the page, reset it for the next use
    await page.evaluate(() => window.stop())
    await page.setContent('<html></html>')
  }
})
