You can receive notifications of new messages when using WhatsApp Web. Notifications will appear on the right side of your computer’s desktop.
There are several reasons why you do not receive notifications from WhatsApp Web:
Follow the on-screen instructions and select Allow to enable notifications from WhatsApp Web.
If you don’t see the blue box, try refreshing the page. If you continue to not see the field, you may have disabled or blocked notifications from WhatsApp Web.
To allow WhatsApp Web to send notifications
To completely disable notifications, start WhatsApp Web, click on the Menu button, select Notifications, turn off Sounds and Alerts on the desktop.
To turn off notifications for a specific time, go to Notifications> Turn off alerts and sounds on ... and select the desired time period.
If you want to enable notifications again, just click on the Disabled notifications icon next to the New chat icon.
Attention: your phone has the Silent function for group chat notifications. If you turn off the notification sound for a group on your phone, the sound will be muted on WhatsApp Web as well. All other settings on the phone and computer are independent of each other.
Set notifications in browsers: Chrome | Firefox | Opera
Good luck
