12.2 KDE Chrome gmail notifications not working.

I have a new clean install of 12.2 KDE with Google Chrome set as the default browser.
Despite configuring Google Chrome correctly the notifications of new mail in gmail are not showing up as a pop-up like they do on my 12.1 install on a different machine.
What further must I do to get them to work on 12.2?
Any ideas or clues? My searches have yielded no results.

Chromium may do a better job than chrome

Thanks for the suggestion but I am running Chrome stable.
I’d be better off staying with what I have and use across multiple systems.
I’ll keep looking for an answer.
