Need help with page concurrency

class PageManager
{
    constructor()
    {
        this.validator = new Validator()
    }

    async acceptOffers(offers, pageNavigator, newInjectedPage, pageSettings) 
    {
        for (let offer of offers)
         {
          const isAcceptable = this.validator.checkRequirements(offer)
          if (isAcceptable)
           {
              const page = newInjectedPage(pageSettings)
              const navigator = new pageNavigator()
              await navigator.acceptOffer(offer.hash)
              await navigator.closePage()
              Logger.log(isAcceptable, offer)
           } else {
            Logger.log(isAcceptable, offer)
              }
}
        
    }
