How to use bus.notify()

[xar]

Hello.

I’d like to display a popup message box when a field is updated.
I tried in the same way that the one in tytond docs, but nothing appends in both clients.
What am I doing wrong ?

from trytond.bus import notify
...
def on_change_field(self):
    if some_checks:
       notify('Title','Body...')

The bus must be activated with allow_subscribe of server configuration.
The notification does not work for desktop client on Windows nor MacOS.

Thank you Cédric !
I never noticed the bus section in config file…
