[Ubuntu 22.04] Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.asamk.Signal was not provided by any .service files

[cloudengineer89]

I'm trying to send a message via dbus service and I am faced with an error: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.asamk.Signal was not provided by any .service files after the command:
dbus-send --system --type=method_call --print-reply --dest="org.asamk.Signal" /org/asamk/Signal/_380931112233 org.asamk.Signal.sendMessage string:"Message text goes here" array:string: string:+380662223344
Please help me to find out where is the problem.

btw when I put --session instead of --system I've got different error: Failed to open connection to "session" message bus: /usr/bin/dbus-launch terminated abnormally without any error message

Here is my result after executing systemctl status dbus:
