impossible to disable notification

[moxgreen]

Describe the bug

I'm trying to disable notification as described here https://copyq.readthedocs.io/en/latest/faq.html#how-to-enable-or-disable-displaying-notification-when-clipboard-changes. But I can't disable them, even if I put 0 for “Interval in seconds to display notifications” and for “Number of lines for clipboard notification”. Both for native and non natative notification modes.

To Reproduce

sudo add-apt-repository ppa:hluk/copyq
sudo apt update
sudo apt install copyq

Open Preference and put 0 for “Interval in seconds to display notifications” and for “Number of lines for clipboard notification”

Expected behavior Non notification nor sound should be emitted when copying something.
