New mail notification by Android PWA?

[datasysnet]

Hello,

I realized today that there is PWA available which works pretty well on my mobile. You should promote that much more showing the differences with and without using PWA i.e. with some screenshots on your website!

Just one question: Is it possible to be notified of new mails arrived on my GO inbox by showing informational messages on the GO icon itself (the amount of new mails in the inbox) and/or displayed on the mobile lockscreen?

Installing the PWA it was asking me to "allow Desktop-Notifications from Group-Office". But after getting new mails in my inbox no notification is taking place (while loggend into GO) on my Android mobile, just sound is being played after logging into GO if there is new mail in the inbox.

Kind regards, Walter
