Is it possible to show the Connection Lost notification from python code in V13?

I want to be able to click a button and show this notification that there is no data available.

I know it can be done from Javascript, but i am trying to show it at the click of a button. I do not wish to raise a UserError or ValidationError or a Warning...

I also tried to do,

def show_notification(self):
    
    return {
        'type': 'ir.actions.client',
        'tag': 'display_notification',
        'params': {
            'title': _('No Information!'),
            'message': 'Cannot find any data right now. Please try again later!',
            'sticky': False,
        }
    }

but it does not do anything!
