System: OpenSUSE Tumbleweed 20190215

I use commands in KDE Connect like Shutdown, Lock Screen, Unlock Screen and it works on Leap 15 and Tumbleweed.
Volume Down, Volume Up and Mute works only on Leap 15.
Should I use another commands for volume control in Tumbleweed?

I use commands from https://userbase.kde.org/KDE_Connect...seful_commands
