Vallox SE Binding

Problem with manual installation of the binding „vallox-3.3.0-SNAPSHOT.jar“ on the Openhab 3.2 system.
Actual status:
I´m running the the Openhab 3.1 with the Binding „vallox-3.1.0-SNAPSHOT.jar“ on a RaspberryPi4. It works fine. I remember that I copied the Binding „vallox-3.1.0-SNAPSHOT.jar“ in the addons folder. After that the binding appears as a thing.
Now I updated to Openhab 3.2. After the update the Vallox binding is „uninizialized“ and the only option I have is to remove the complete binding.
To validate the situation I setup a new Openhab 3.2 version on the RaspberryPi4. I copied the binding „vallox-3.3.0-SNAPSHOT.jar“ in the addons folder but nothing happens.
Can somebody help me what I need to do next step by step? I already read some posts how to modify the „addons.cfg“ file and typed some commands in the Karaf but without luck.
