Bluetooth config in docker container doesn't show?

I have followed the instructions here Bluetooth - Home Assistant
but it seems the integration cannot be loaded ? It just says ‘No Unconfigured Bluetooth adaptors found’
I checked and the adaptor is visable to the docker container but using the bluetoothctl command from within the container does not work? Output below. Any help would be appreciated, host system is Alma Linux 8.6. I am using the ZEXMTE BT-505 listed as recommended.
