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.

Additional context

How do the notifications looks like? Most of the settings is to disable notifications for clipboard changes, other popups would still show up (mainly for errors or warnings).

Do you use any commands that call popup or notification? You can look up these in Commands dialog (F6 shortcut) and searching for those terms (in the Find field at the bottom of the dialog).
