Notifications > refresh problem ?

When I'm in the "notification" tab and waiting for someone to add my library to approve their request there's a label that appears in the menu but nothing on the notifications page. I have to leave the page, then come back, to see the notification.

I don't know if it's technically impossible to display the notification without refreshing the page? Maybe a refresh button in this case?

Here I am waiting for the request, a label appears in the menu but nothing in the page.

I click elsewhere in the menu to return to see the notification. (I didn't try to click in the label to see if it reloaded the page.)
