As title says --next-key-info is not working since version 5.1.0 for me, I'm on Linux Mint 22.2 Cinnamon
when I run keymapperctl --next-key-info in the terminal I don't get the expected output

And --no-notify and even @options no-notify don't work 'cause I still get the configuration updated notification
making the notification transient may help so I don't end up with a lot of notifications when updating my config.
