Customer App notification sound

Hi! Community

Kindly advice on how to set up notifications for a customer web app. If the driver has arrived how does one notifies the customer and how to make that notification loud so that the customer hears a sound notifying her of the arrival of the driver at the pick point?

Dear @Seedwell13,

Kindly note that user authorization in Web app is possible via phone number only. There’s no technical way to send notifications to web app users. It is supposed that a user tracks order status updates in the web app just as he does in a mobile customer app.
