How to connect my onboard Bluetooth to a HA docker under unraid

I’m already busy for a week to find out how to get my onboard bluetooth connected to HA.
I’m runnig HA as a docker container under Unraid.
My server is a Geekom IT13
It is working fine, but I’m not able to connect the bluetooth to my HA docker.
If I look into the HA Bluetooth integration documantation it says to install Bluez and dbus.
If I start the bluetooth integration in HA it indeed says missing Dbus.


My Question is how to connect the onboard Bluetooth USB to my HA docker under Unraid.
And how to install Bluez and Dbus for the HA docker?

If I look at the USB plugin I do see the bluetooth in the list

Any help is appriciated
