Error message "device doesn't answer" or "device not connected" (sorry, German user) should be deleted after successful connecting

blueman: 2.4
BlueZ: ??
Distribution: Linux Mint 22
Desktop environment: Cinnamon 6.2.9

I switched on blueman-manager and clicked to connect my headset.
As it was not in pairing mode, the appropriate error message was shown.
Switched headset into pairing mode and click the headset in the list, connected.

The error message is kept being displayed. This should be changed as it is confusing to read it after successful connection.
