Bluetooth won't connect inside docker container

I’m having trouble with bluetooth in my docker config. It used to work, but I’m not sure when it stopped.

Bluetooth works in ubuntu, but I get this error when I try inside the container:

bash-5.0# bluetoothctl
dbus[2784]: arguments to dbus_connection_get_object_path_data() were incorrect, assertion "connection != NULL" failed in file dbus-connection.c line 5905.
This is normally a bug in some application using the D-Bus library.

  D-Bus not compiled with backtrace support so unable to print a backtrace
Aborted (core dumped)

As I have understood the bluetooth should go through to the docker container when I have net=host.

I have a NUC5i5MYHE with a added wifi/bt card ( https://ark.intel.com/content/www/us/en/ark/products/83635/intel-dual-band-wireless-ac-7265.html ). It states:
System Interface Type Wi-Fi(PCIe), BT(USB)

Do I need to “mount” this a device in my docker-compose for HA because it is USB? I have tried to bind it to “ttyUSBbt” by editing 99-usb-serial.rules but no luck. I have tried to mount the device in docker-compose but no luck

devices:
  - /dev/bus/usb/002/006:/dev/ttyBT

How do I connect to my bluetooth inside the HA-container?
