Bluetooth remote not working inside kodi (raspbrian)

Hi I have a bluetooth remote (fire tv stick). I’ve paired it Inside rasbrian but once i launch kodi it doesnt control anything, the key rebinder addon doesnt even pick up the inputs. I know its working as it can control the raspbrian pixel GUI.

Im hoping there is a simple switch ive missed somewhere to allow kodi to see the bluetooth device and/or a way to pair it to kodi directly?
